In this paper, we prepared Al2O3–ZrO2–SiB6 composite ceramics with excellent performance by introducing the second‐phase high‐strength healing agent SiB6 in zirconia‐toughened alumina system, artificially created cracks using Vickers hardness tester, investigated the effects of heat treatment temperature (600–1200°C) and time (0–300 min) on the microscopic morphology and bending strength of the ceramics, revealed the healing mechanism, and studied the oxidation resistance properties. It was found that the healing effect was better at heat treatment of 90 min at 700°C and 60 min at 800°C, and the flexural strength was restored to more than 95% of that of the smooth specimens in both cases. Crack repair was mainly achieved by the reaction of SiB6, ZrB2, and B4C with O2. Below 800°C, healing was mainly achieved by the reaction of SiB6 and B4C with O2, and the generated B2O3 and SiO2 migrated toward the crack to repair it. When the healing temperature is higher than 800°C, ZrB2 also reacts with oxygen to produce B2O3 and t‐ZrO2. It was found that the oxidation weight gain per unit area of the Al2O3–ZrO2–SiB6 ceramic composite at different temperatures was small, and it has excellent oxidation resistance.
本文通过在氧化锆增韧氧化铝体系中引入第二相高强度愈合剂SiB6,制备了性能优异的Al2O3-ZrO2-SiB6复合陶瓷,利用维氏硬度计人为制造裂纹,研究了热处理温度(600-1200℃)和时间(0-300min)对陶瓷微观形貌和抗折强度的影响,揭示了愈合机理,并研究了抗氧化性能。研究发现,在 700°C 热处理 90 分钟和 800°C 热处理 60 分钟时,修复效果较好,两种情况下的抗弯强度均恢复到光滑试样的 95% 以上。裂缝修复主要是通过 SiB6、ZrB2 和 B4C 与 O2 的反应实现的。低于 800°C 时,愈合主要是通过 SiB6 和 B4C 与 O2 的反应实现的,生成的 B2O3 和 SiO2 向裂纹迁移以修复裂纹。当愈合温度高于 800°C 时,ZrB2 也会与氧气发生反应,生成 B2O3 和 t-ZrO2。研究发现,Al2O3-ZrO2-SiB6 陶瓷复合材料在不同温度下的单位面积氧化增重很小,具有优异的抗氧化性。

A porous silicon carbide (SiC) ceramic filter was prepared at 1000°C using waste red mud (RM), SiC, pore‐forming agent, and catalyst. The influence of sintering temperature, RM content, and pore former on the mechanical performance and the porosity of porous ceramics were investigated, and based on the result optimal processing parameters were selected. The air and water permeability tests were carried out at room temperature. The stability of the ceramic filter under thermal shock and chemical treatment was investigated and corroded samples were characterized. The ceramic was prepared using optimized processing parameters obtained with a flexural strength of 65.36 MPa at a porosity of 30.15 vol.% and demonstrated good performance in terms of pure water flux, oil, and turbidity removal efficiency from industrial wastewater. The filtration and permeation results indicated that the SiC filter prepared in this study is suitable for various applications, particularly in the remediation of oil‐polluted water.

The present study intends to establish biphasic composite scaffolds containing polycaprolactone/hydroxyapatite (PCL/HA) and PCL/barium titanate (PCL/BT) layers with improved mechanical and biological properties by preserving HA and tuning BT contents. The porous piezo‐biphasic scaffolds were fabricated, using extrusion three‐dimensional printer technology, and on the basis of the scanning electron microscopy results, a relative porosity of 210–250 µm was created. The presence of BT phase in the biphasic scaffolds was confirmed by X‐ray diffraction and Fourier transform infrared analyses. The printed biphasic composites demonstrate suitable mechanical strength compared to one containing only 35% PCL and 65% HA compositions, which had a strength of 2.5 MPa. However, the strength for 80% BT‐incorporated biphasic composite was almost 13.5 times higher than that of monolithic specimen. The measured output voltages for the scaffolds after being subjected to an electric field affirmed that adding BT nanoparticles in biphasic composites leads to an increase in the output voltage that was lower compared to the monolithic scaffold. The piezo‐biphasic scaffold containing 80% BT is found to possess the highest enhancement in cytocompatibility for MG63 cells with the survival rate of approximately 95%, rendering the PCL/HA–PCL/BT biphasic scaffolds promising candidates for bone regeneration.
本研究旨在通过保留 HA 和调整 BT 的含量,建立含有聚己内酯/羟基磷灰石(PCL/HA)层和 PCL/钛酸钡(PCL/BT)层的双相复合支架,以改善其机械和生物特性。利用挤压式三维打印机技术制作了多孔压电双相支架,根据扫描电子显微镜结果,其相对孔隙率为 210-250 µm。X 射线衍射和傅立叶变换红外分析证实了双相支架中 BT 相的存在。与仅含 35% PCL 和 65% HA 成分的双相复合材料相比,打印出的双相复合材料具有合适的机械强度,后者的强度为 2.5 兆帕。然而,80% BT 加入的双相复合材料的强度几乎是单片试样的 13.5 倍。支架在电场作用下的输出电压测量结果表明,在双相复合材料中添加 BT 纳米粒子可提高输出电压,但输出电压低于单片支架。研究发现,含有 80% BT 的压电双相支架对 MG63 细胞的细胞相容性有最高的增强效果,存活率约为 95%,因此 PCL/HA-PCL/BT 双相支架有望用于骨再生。

In this study, varying amounts of MnO2 up to 5 wt.% were added to magnesium aluminate spinel (MA) bodies using a solid‐state sintering method at 1200–1600°C. The effect of MnO2 addition on the phase composition, microstructure, distribution of elements, and ionic valence of MA was investigated via X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, and X‐ray photoelectron spectroscopy, respectively. The results showed that Mg2+ ions in MA crystals were replaced by Mn2+ ions, resulting in the formation of the (Mg1‐xMnx)Al2O4 solid solution. The distorted crystal structures promoted the sintering reactions, and the mechanical characteristics of MA were greatly improved by the solid solution strengthening process. When the additive amount of MnO2 was 5 wt.% and the sintered temperature reached at 1600°C, excess manganese ions hardly dissolved into the lattice of MA. And these ions were only distributed at the grain boundaries of MgAl2O4, forming a “barrier” that hindered the migration and diffusion of particles, thereby suppressing the sintering process and weakening the mechanical strength of MA.
在本研究中,采用固态烧结法在 1200-1600°C 下向铝酸镁尖晶石(MA)体中添加了不同量的 MnO2,最高达 5 wt.%。通过 X 射线衍射、扫描电子显微镜、能量色散光谱和 X 射线光电子能谱分别研究了 MnO2 的添加对尖晶石镁体的相组成、微观结构、元素分布和离子价的影响。结果表明,MA 晶体中的 Mg2+ 离子被 Mn2+ 离子取代,形成了 (Mg1-xMnx)Al2O4 固溶体。扭曲的晶体结构促进了烧结反应,固溶强化过程大大改善了 MA 的力学特性。当 MnO2 的添加量为 5 wt.%、烧结温度达到 1600°C 时,过量的锰离子很难溶解到 MA 的晶格中。这些离子只分布在 MgAl2O4 的晶界上,形成了阻碍颗粒迁移和扩散的 "屏障",从而抑制了烧结过程,削弱了 MA 的机械强度。

In this study, we investigated the impact of polyethylene glycol, sodium carboxymethyl cellulose, and polyvinyl alcohol on the rheological behavior, printability, and mechanical/physical properties of 3D‐printed scaffolds for high‐temperature applications using SiC/clay ceramic paste. Employing the Direct Ink Writing method, varying concentrations of each polymer (PEG: 2.5%–10% weight, CMC: .6%–1.8% weight, PVA: .25%–1% weight) were incorporated into the composition. The resulting SiC/clay paste, with adjusted additive content, was used to 3D‐print scaffold structures through Direct Ink Writing. Sintering of clay‐bonded SiC samples were carried out at 1300°C for 1 h in an ambient atmosphere. The research revealed that altering the additive amounts significantly influenced the rheological behavior, mechanical properties, and physical characteristics of the printed specimens. Notably, the ideal properties with additive concentrations (10% wt PEG, 1% wt PVA, and .6% CMC) were identified, providing the best outcomes in terms of printability and firing results. High density samples with 2.09, 1.93, and 1.79 g/cm3, high compression strength of 20.82, 14.5 and 12.53 MPa with 32.26%, 42.5%, and 52.63% open porosity for samples containing PVA, CMC, and PEG modifiers were obtained, respectively. Additionally, the study led to the development of a high solid loading printable paste with an 80% weight.

The corrosion of SiCf/SiC composites in gas environment threatens their long‐term service in aeroengines as hot‐end structure components. Addition of corrosion‐resistant phases into SiC matrix is a potential strategy to improve the service performance of SiCf/SiC materials. Here, AlN added SiC ceramics were prepared by reactive melt infiltration, and the effect of AlN phase on the oxidation resistance of the ceramics was emphasized. The oxidation tests were performed in dry oxygen and water oxygen atmospheres at 1100°C–1300°C, respectively. The oxidation mechanism was discussed based on the microstructure evolution of the oxide layer. The results show that the oxide layer is composed of aluminum silicate glass and Al2O3 flakes dispersedly distributed in the glass phase. As the temperature rises, the oxide layer gradually grows and thickens. Finally, a smooth and dense protective layer could be formed on the surface of ceramics to resist oxidation. This study can provide a profound insight to construct SiCf/SiC composites with excellent oxidation resistance.
SiCf/SiC 复合材料在气体环境中的腐蚀威胁着其在航空发动机热端结构部件中的长期使用。在 SiC 基体中添加抗腐蚀相是改善 SiCf/SiC 材料服役性能的潜在策略。本文采用反应熔渗法制备了添加 AlN 的 SiC 陶瓷,并重点研究了 AlN 相对陶瓷抗氧化性的影响。氧化试验分别在 1100°C-1300°C 的干氧和水氧气氛中进行。根据氧化层的微观结构演变讨论了氧化机理。结果表明,氧化层由硅酸铝玻璃和分散分布在玻璃相中的 Al2O3 薄片组成。随着温度的升高,氧化层逐渐增大变厚。最后,陶瓷表面形成了光滑致密的保护层,从而起到抗氧化的作用。这项研究为构建具有优异抗氧化性的 SiCf/SiC 复合材料提供了深刻的启示。

To solve the problem that Si was volatile and dense Si/SiC ceramics were difficult to achieve by spark plasma sintering (SPS) under a low sintering temperature and pressure, three kinds of SiC powders were used for particle grading and then ball‐milled with different time to further change and regulate their particle size and morphology, and finally nearly dense Si/SiC ceramics were prepared by SPS. The effect of milling time on particle size, morphology, tap density, phase, and microstructure of the SiC powders, as well as on bulk density, microhardness, thermal conductivity, phase, and microstructure of the Si/SiC ceramic, was researched. When the mixed SiC powders were ball‐milled for 12 min, the bulk density, microhardness, and thermal conductivity of Si/SiC ceramic were 2.96 g/cm3, 22.95 GPa, and 152.84 W/(m K), respectively. Ball milling changed the particle gradation and micro‐powder morphology and then affected the powder particle stacking state. Forming continuous pore channels was conducive for the volatile liquid Si to flowing and filling pores in a short time, resulting in denser Si/SiC ceramics at a lower sintering temperature and pressure. This study was useful for the preparation of ceramics containing volatile liquid phase by SPS.
为了解决硅易挥发、低烧结温度和压力下火花等离子体烧结(SPS)难以制备出致密的 Si/SiC 陶瓷的问题,采用三种 SiC 粉末进行颗粒分级,然后用不同时间的球磨进一步改变和调节其粒度和形貌,最终用 SPS 制备出近乎致密的 Si/SiC 陶瓷。研究了研磨时间对 SiC 粉末的粒度、形貌、敲击密度、相和微观结构的影响,以及对 Si/SiC 陶瓷的体积密度、显微硬度、热导率、相和微观结构的影响。将混合碳化硅粉末球磨 12 分钟后,Si/SiC 陶瓷的体积密度、显微硬度和热导率分别为 2.96 g/cm3、22.95 GPa 和 152.84 W/(m K)。球磨改变了颗粒级配和微粉形态,进而影响了粉末颗粒的堆积状态。形成连续的孔道有利于挥发性液态 Si 在短时间内流动并填充孔隙,从而在较低的烧结温度和压力下获得致密的 Si/SiC 陶瓷。这项研究有助于利用 SPS 制备含有挥发性液相的陶瓷。

Does a relationship exist between hardness and compression strength for advanced ceramics? 先进陶瓷的硬度和压缩强度之间是否存在关系?

The Knoop hardness (HK) and compression strength (σc) of 23 advanced ceramics were measured to determine if an overarching HK/σc relationship could be identified for ceramics, or if one exists for a specific class of ceramics, similar to the hardness/yield strength relationship (H/Y ≈ 3) identified by Tabor for metals. Compression strength was determined using a dumbbell‐shaped specimen that virtually eliminates the end splitting that occurs when cylinders or cuboids are tested and provides a more representative compression strength value. HK values were obtained over a range of indentation loads between 0.98 and 98N. Four HK values, HK2, load‐independent HK, the hardness from the proportional specimen resistance model, and a brittleness parameter, were obtained and plotted against compression strength. An overarching relationship could not be identified for ceramics in general and the only class of ceramics that had a consistent relationship was tungsten carbide/cobalt that had a HK/σc of approximately 2.5. The consistent relationship for the WC/Co materials is due to the cobalt plastically deforming during the loading processes, something that does not occur in the other ceramics evaluated.
对 23 种先进陶瓷的努氏硬度 (HK) 和压缩强度 (σc)进行了测量,以确定是否可以为陶瓷确定一个总体的 HK/σc 关系,或者是否为特定类别的陶瓷确定一个总体的 HK/σc 关系,类似于 Tabor 为金属确定的硬度/屈服强度关系 (H/Y ≈ 3)。抗压强度是用哑铃形试样测定的,这种试样实际上消除了测试圆柱体或立方体时出现的端部劈裂现象,并提供了更具代表性的抗压强度值。在 0.98 至 98N 的压痕载荷范围内获得了 HK 值。获得了四个 HK 值,即 HK2、与载荷无关的 HK、试样电阻比例模型得出的硬度以及脆性参数,并将其与压缩强度绘制成图。一般来说,无法确定陶瓷的总体关系,唯一具有一致关系的陶瓷类别是碳化钨/钴,其 HK/σc 约为 2.5。碳化钨/钴材料的一致关系是由于钴在加载过程中发生了塑性变形,而其他被评估的陶瓷则没有发生这种情况。

Fiberboard (FB) is extensively utilized in heat‐insulating refractory materials owing to its lightweight nature and excellent resistance to high temperatures. Nevertheless, the inadequate mechanical properties and limited dimensional stability of FB hinder its further application. The vacuum filtration was utilized in this study to manufacture inorganically modified insulation FB, incorporating plus fiber/1260 fiber and silica sol as the primary constituents and sepiolite powder (HS) as the modifier. The experimental results show that the fabricated samples exhibited extremely high porosity (75.3%–90.2%) and low thermal conductivity (.063–.15 W m−1 K−1, 200–800°C). The fibers were arranged in a three‐dimensional structure, overlapping with each other, and the silica sol adhered to the fibers, forming a spatial mesh structure through cross‐linking. Importantly, the incorporation of HS was effective in controlling the agglomeration of the silica sol, leading to a more uniform distribution within the fibers. Additionally, the study found that the mechanical properties (high hardness (64–72 HA)) and high‐temperature durability of the FBs were enhanced due to the flocculant modification. This study highlights promising prospects for industrial applications and offers a cost‐effective admixture for modifying and preparing high‐performance FBs, which is expected to see broad adoption in thermal insulation and energy conservation applications.
纤维板(FB)因其轻质和出色的耐高温性能而被广泛应用于隔热耐火材料中。然而,纤维板机械性能的不足和有限的尺寸稳定性阻碍了它的进一步应用。本研究利用真空过滤法制造了无机改性隔热 FB,以 plus 纤维/1260 纤维和硅溶胶为主要成分,以海泡石粉末(HS)为改性剂。实验结果表明,制造出的样品具有极高的孔隙率(75.3%-90.2%)和较低的热导率(0.063-0.15 W m-1 K-1,200-800°C)。纤维呈三维结构排列,相互重叠,二氧化硅溶胶附着在纤维上,通过交联形成空间网状结构。重要的是,HS 的加入能有效控制硅溶胶的团聚,使其在纤维内的分布更加均匀。此外,研究还发现,由于絮凝剂的改性,FB 的机械性能(高硬度(64-72 HA))和高温耐久性都得到了提高。这项研究强调了工业应用的广阔前景,并为改性和制备高性能 FB 提供了一种具有成本效益的外加剂,有望在隔热和节能应用中得到广泛采用。

The social progress, economic growth, and meteoric urbanization prompt the exploitation of available resources triggering the contagion of the biological and physical elements of the atmosphere irrationally causing global environmental pollution. Environmental contamination monitoring is a dire necessity. Although a number of technologies find mention in the literature for environmental remediation, however, environmental catalysis is an advanced steadily growing technique for pollution abatement. In this dimension, ceramic materials have turned heads due to their wide-scale application areas. Hitherto, research is being done on advanced ceramics to fabricate novel modules for energy storage applications, in designing green buildings, pollution rheostats, and environmental engineering. This article deals with the abatement of environmental contaminants by adopting various methodologies such as aerobic and anaerobic biological treatments, adsorption, chemical oxidation, membrane separation, photocatalysis, ozonation using the ceramic as precursor materials. The ceramic membranes are cost-effective, ecofriendly, efficacious, and green approach to obliterate toxins and harmful gases released in environment. Even though, limited literature is available on the abolition of harmful contaminants from air and soil using ceramic materials, an attempt has been made to present currently available data with best of our knowledge. This article will sensitize researchers to refabricate novel materials for environment sustainability.

社会进步、经济增长和飞速发展的城市化,促使人们对现有资源的开发利用,引发了大气中生物和物理元素的传染,不合理地造成了全球环境污染。环境污染监测已成为当务之急。尽管文献中提到了许多环境修复技术,但环境催化技术是一种先进的、稳步发展的污染消除技术。在这方面,陶瓷材料因其广泛的应用领域而备受瞩目。迄今为止,人们正在对先进陶瓷进行研究,以制造新型模块,用于能源储存、绿色建筑设计、污染控制和环境工程。这篇文章论述了以陶瓷为前驱材料,通过采用各种方法(如好氧和厌氧生物处理、吸附、化学氧化、膜分离、光催化、臭氧)来减少环境污染物。陶瓷膜是一种具有成本效益、生态友好、高效和绿色的方法,可消除环境中释放的毒素和有害气体。尽管有关使用陶瓷材料消除空气和土壤中有害污染物的文献资料有限,但我们还是试图以我们所掌握的最佳知识来介绍目前可用的数据。这篇文章将促使研究人员重新制造新型材料,以实现环境的可持续发展。
