Research on reinforced metakaolin-based geopolymers for structural applications is reviewed. Geopolymers have been synthesized using metakaolin produced from kaolinite extracted from several regional soils. Kaolin is converted into metakaolin by calcination from 650 °C up to 800 °C. To obtain higher strength and stiffness, the geopolymer matrix is reinforced with particles and fibers. In addition, synthetic and natural particles and fibers have been used to enhance durability, thermal properties and shrinkage ratio of lighter geopolymer composites. Owing to the unavailability of a standard for processing and testing geopolymer composites, different laboratories use differing procedures, making data comparison very difficult. The promising market of geopolymer composites for the sustainable construction industry would benefit from a uniform standard for laboratory processing and testing. This would contribute to the creation of a large and reliable data bank, and facilitate the manufacture and certification of geopolymeric sustainable construction materials.

For future stationary energy storage requirements, sodium batteries are potentially suitable candidates owing to their high energy density, proven reliability, high faradaic efficiency and the use of abundant low-cost raw materials. Tubular battery designs require a thin-walled solid electrolyte tube, usually formed from ion-conductive beta′′-alumina ceramic. State-of-the-art manufacturing methods, namely isostatic pressing and electrophoretic deposition, contribute a significant proportion of battery cost, and it is desirable to identify a high-volume low-cost process for the ceramic. Extrusion offers the potential for a rapid low-cost, high-volume production process but requires special development for adaptation to the demands of solid electrolyte production. This paper summarizes recent trials on extrusion as a process for producing beta′′-alumina ceramic electrolyte tubes.

Granulation is a key factor towards improvement of the flowability of fine ceramic powders to make them suitable for industrial dry pressing. Controlled granulation of fine alumina particles with a primary particle size of ∼ 150 nm was carried out using spray-freeze drying, which led to the production of flowable granules with high crushability. The fracture surface of uniaxially die-pressed green bodies made from granules with density values of ≥ 50%of theoretical showed a uniform microstructure. Sintering experiments were performed using conventional single- and two-stage radiant heating methods followed by density and grain size measurement and characterisation of the final dense compacts to study the efficiency of two-stage sintering in grain growth elimination. The results have been compared with those of alumina bodies prepared using similar suspension by the slip-casting route.

In situ applied-electric-field high-resolution X-ray diffraction has been used to study the field-induced response of Mn-doped (K 0.48 Na 0.48 Li 0.04 )NbO 3 (KNN-L) ceramics produced using the conventional mixed-oxide processing route. Ferroelectric domains are observed with transmission electron microscopy with indications of nano-segrega-tion of Mn. Rietveld refinement (FULLPROF Suite) is used to refine the diffraction patterns, and a phase change from orthorhombic symmetry with space group A mm 2 to tetragonal symmetry with space group P4 mm is observed when the applied field exceeds 1.4 kV/mm. Phase coexistence between the two phases is also observed at applied fields between 1.2 kV/mm and 1.3 kV/mm with possible implications of being the coercive field E C value of the sample. A better understanding of the structural behaviour of this type of lead-free ceramics will lead to improvements in their piezoelectric and electromechanical properties.
采用原位施加电场高分辨率x射线衍射研究了采用常规混合氧化物工艺制备的mn掺杂(K 0.48 Na 0.48 Li 0.04) nbo3 (KNN-L)陶瓷的场致响应。铁电畴用透射电子显微镜观察到锰的纳米偏析迹象。利用Rietveld细化(FULLPROF Suite)技术对衍射图进行了细化，发现当外加电场超过1.4 kV/mm时，衍射图由空间群a mm 2的正交对称变为空间群P4 mm的四方对称。在1.2 kV/mm和1.3 kV/mm之间的电场中也观察到两相之间的相共存，这可能意味着样品的矫顽力场E - C值。更好地了解这种类型的无铅陶瓷的结构行为将导致其压电和机电性能的改善。

Based on industrial ZrSiO4 glazes for sanitaryware, a new glaze with photoactive oxides was developed. The development aimed to produce a glaze that is smooth in order to decrease contamination of the ware and increase superhydrophilic wetting behaviour for easier cleanability. The glazes were characterized with profilometry, atomic force microscopy, x-ray diffraction and scanning electronmicroscopy. For reactivity under UV light, the wetting angles in the dark and after irradiation, aswell as the degradationofmethylene blueweremeasured. SampleswithTiO2 showed no improvement in wetting, neither in the dark, nor under UV irradiation. However, compared with the industrial ZrSiO4 tile, the cleaning properties were improved in the case of bulk contaminants likemustard. Evenmore promising resultswere achieved by replacingZrSiO4withZnO.The glazes developed in thiswork showed surface roughness of less than 20 nm and superhydrophilic wetting under UV illumination.

This work correlates damping measurements and the microstructural changes in refractory castables after these have been exposed to thermal shocks in air. In accordance with DIN EN 993 – 11, refractory samples based on tabular alumina with the addition of partially stabilized zirconia (PSZ) were progressively subjected to thermal shocks in air at different temperatures (750, 850, 950 and 1050 °C). White fused alumina samples were also exposed to the same thermal shocks at 950 °C. Evaluation of the thermal shock damage to the high-alumina refractory castables was based on the dynamic Young‘s modulus and damping characterization data obtained by means of the impulse excitation technique (IET), in accordance with ASTM E1876 – 07. Scanning electron microscopy (SEM) was also performed to enable understanding of the elastic changes in these refractory formulations. The results show that the damping increase in PSZ castables may be explained by crack nucleation and propagation while such phenomena do not occur in WFA castable.
这项工作将阻尼测量和耐火浇注料暴露于空气中的热冲击后的微观结构变化联系起来。根据DIN EN 993 - 11，基于片状氧化铝和添加部分稳定氧化锆(PSZ)的耐火材料样品在不同温度(750、850、950和1050℃)的空气中逐渐受到热冲击。白色刚玉样品也暴露在950°C的相同热冲击下。根据ASTM E1876 - 07标准，基于脉冲激励技术(IET)获得的动态杨氏模量和阻尼表征数据，对高铝耐火浇注料的热冲击损伤进行了评估。扫描电子显微镜(SEM)也进行了，以使了解这些耐火配方的弹性变化。结果表明，PSZ浇注料的阻尼增加可以用裂纹形核和扩展来解释，而WFA浇注料则没有这种现象。

The thermal shock behaviour of novel carbon-reduced refractories with maximum grain size of 1 mm was investigated. A wedge splitting test for small specimen geometries (max. 40 × 40 × 20 mm 3 ) was successfully implemented with different loading configurations to determine “work of fracture” and thermal shock parameters. Additionally, heating-up thermal shock tests were performed with an electron beam facility. The addition of 2.5 wt% ZrO 2 and TiO 2 to Al 2 O 3 refractories appears to improve their thermal shock resistance due to microstructural changes that reduce brittleness and inhibit critical crack growth. However, a phase transition of ZrO 2 affects the properties at elevated temperature. For another pure alumina refractory, no geometry-independent value for the work of fracture could be obtained for the sample geometry used, which is probably related to the formation of a large interaction zone of the fracture surfaces. Al 2 O 3 -C materials with addition of semi-conductive Si and nanoparticles revealed a strong effect of the pressing direction on the work of fracture. However, the thermal shock parameter R’’’’ was hardly affected by the different additives. Furthermore, thermal shock tests using the electron beam facility JUDITH 1 did not indicate any significant differences in the damage pattern of the different Al 2 O 3 -C materials.
