Understanding the physical and chemical characteristics of fluorine-containing blast furnace slag is crucial for using fluorine-bearing ores in blast furnace melting. This paper comprehensively analyzes the effects of CaF₂ on the viscous flow characteristics and structural changes of CaO-SiO₂-MgO-Al₂O₃-CaF₂ blast furnace slag at 1773K. Viscosity measurement results suggest that a higher concentration of CaF₂ contributes to a reduction in slag viscosity. Increasing the CaF₂ content consistently decreases the viscosity of the slag, though the magnitude of this effect diminishes with higher CaF₂ levels. FT-IR shows changes in structure: the diminishing intensity of the [SiO₄]-tetrahedral vibration band and the T-O-T bond strength, shallowing of the groove depth. Besides, a slight narrowing of the shoulder width of the [AlO₄]-tetrahedral structure, but the change is insignificant. Raman results indicate a depolymerization of Si-based structural units. As the CaF₂ content increases from 0 % to 4 %, there is a rise in simpler Q⁰ and Q¹ structural units and a reduction in more complex Q² units. The Q³ structural units show a decreasing trend, without significant change upon further increase. The ratio of non-bridging oxygen to silicon (NBO/Si) increases from 1.95 to 2.28 with the addition of CaF₂, suggesting a lower level of slag polymerization. Fluorine ion serves as a network modifier within the slag structure. XPS results show a decline in the relative concentration of bridging oxygen, whereas the relative concentrations of NBO and free oxygen increase. Finally, ²⁷Al MAS NMR reveals that adding CaF₂ reduces the proportion of [AlO₄] and raises the proportion of [AlO₅] and [AlO₃F] units.

了解含氟高炉渣的物理和化学特性对于在高炉熔炼中使用含氟矿石至关重要。本文全面分析了 CaF2 对 1773K 下 CaO-SiO2-MgO-Al2O3-CaF2 高炉渣粘流特性和结构变化的影响。粘度测量结果表明，CaF2 浓度越高，炉渣粘度越低。增加 CaF2 的含量会持续降低炉渣的粘度，但随着 CaF2 含量的增加，这种影响的幅度会减小。傅立叶变换红外光谱显示了结构的变化：[SiO4]四面体振动带和 T-O-T 键强度减弱，沟槽深度变浅。此外，[AlO4]-四面体结构的肩宽略有缩小，但变化不大。拉曼结果表明硅基结构单元发生了解聚。随着 CaF2 含量从 0% 增加到 4%，较简单的 Q0 和 Q1 结构单元有所增加，而较复杂的 Q2 结构单元则有所减少。Q3 结构单元呈下降趋势，在进一步增加时没有明显变化。加入 CaF2 后，非桥氧与硅的比率（NBO/Si）从 1.95 增加到 2.28，这表明熔渣聚合度较低。氟离子是炉渣结构中的网络修饰剂。XPS 结果显示架桥氧的相对浓度下降，而 NBO 和游离氧的相对浓度上升。最后，27Al MAS NMR 显示，加入 CaF2 会降低 [AlO4] 的比例，提高 [AlO5] 和 [AlO3F] 单元的比例。

At present, volume Bragg grating (VBG) is the core devices in the field of precision optical field modulation, and their performance is mainly influenced by the substrate photothermal refractive (PTR) glass. The liquid phase separation (LLPS) behavior occurring in the base glass can lead to unnecessary scattering losses and have adverse effects on the engineering applications of VBG. In recent years, many glass scientists have conducted research on the liquid-liquid phase separation (LLPS) of glass, believing that the structure of glass phase separation is related to the composition of the glass. This study used high-temperature melting method to prepare Na-Zn-Al-Si PTR glass doped with Ag, Ce, Sn and other elements through two-step heat treatment. In this experiment, the influence mechanism of ZnO on the LLPS of PTR glasses was investigated by controlling the doping amount of ZnO. Modern analysis techniques were used to investigate the mechanism of ZnO on the LLPS, the results confirm that no crystal phase is generated during the glass phase separation in this work, and doping 4 mol% ZnO is beneficial for suppressing the LLPS of PTR glasses. In addition, the introduction of Na₂O by using NaNO₃ can avoid the generation of Ag₂O and Ag₂CO₃ impurities, which is conducive to the precipitation of NaF grains.

目前，体布拉格光栅（VBG）是精密光场调制领域的核心器件，其性能主要受基片光热折射玻璃（PTR）的影响。基底玻璃中发生的液相分离（LLPS）行为会导致不必要的散射损失，对 VBG 的工程应用产生不利影响。近年来，许多玻璃科学家对玻璃的液-液相分离（LLPS）进行了研究，认为玻璃相分离的结构与玻璃的成分有关。本研究采用高温熔融法，通过两步热处理制备掺杂了Ag、Ce、Sn等元素的Na-Zn-Al-Si PTR玻璃。实验中，通过控制氧化锌的掺量，研究了氧化锌对 PTR 玻璃 LLPS 的影响机理。实验采用现代分析技术研究了 ZnO 对 LLPS 的影响机理，结果表明在本实验中玻璃相分离过程中没有晶相产生，掺杂 4 mol% 的 ZnO 有利于抑制 PTR 玻璃的 LLPS。此外，利用 NaNO3 引入 Na2O 可以避免 Ag2O 和 Ag2CO3 杂质的生成，有利于 NaF 晶粒的析出。

The phase diagram of CaO-Al₂O₃-Ti₂O₃ system has significant implications for the metallurgical slag design of Al-Ti alloy steel. In this work, the high-temperature equilibrium experiments were conducted at 1500 °C and 1600 °C in C/CO equilibrium atmosphere, respectively. The types and compositions of the equilibrium phases were determined by Electron Probe Micro Analysis (EPMA) and X-ray diffraction (XRD). The isothermal section of CaO-Al₂O₃-Ti₂O₃ system in the low w(TiO_x) region at 1500 °C was constructed for the first time, in which there are 6 three-phase fields, 7 two-phase fields, and a liquid phase field. The isothermal section of CaO-Al₂O₃-Ti₂O₃ system in the low w(TiO_x) region at 1600 °C was constructed and revised, including 3 three-phase fields, 6 two-phase fields, and a liquid phase field. Additionally, under the current experimental condition, the reasons for the formation of TiC in the high w(TiO_x) region of this slag system were analyzed, further discussing the effect of carbon on the phase equilibria of CaO-Al₂O₃-Ti₂O₃ system.

Using the melt quenching technique, a number of [(TeO₂)₇₀(B₂O₃)₃₀]₇₀(ZnO)₃₀₋ₓ(Gd₂O₃)ₓ glasses were created. The amorphous nature of the glasses was substantiated by X-ray diffraction (XRD), and the existence of GdO₃ nanoparticles was confirmed by transmission electron microscopy (TEM). Key vibrational groups were identified by Fourier-transform infrared (FTIR) spectroscopy: TeO₃, TeO₄, BO₃, and BO₄. The formation of TeO₄ units improved the radiation shielding capabilities of the glasses, especially in TBZG5, which showed superior photon absorption owing to the presence of large Gd³⁺ ions and lone pair electrons. Specifically, the Gd₂O₃ NP-doped glasses showed reverse saturable absorption and self-focusing behaviour with nonlinear absorption coefficients ranging from 0.660 to 0.729 cm/GW. These glasses also showed increasing nonlinear refractive indices coupled with decreasing overall refractive indices.

利用熔体淬火技术，制备出了多种[(TeO₂)₇₀(B₂O₃)₃₀]₇₀(ZnO)₃₀₋ₓ(Gd₂O₃)ₓ玻璃。X 射线衍射（XRD）证实了玻璃的无定形性质，透射电子显微镜（TEM）证实了 GdO₃ 纳米粒子的存在。傅立叶变换红外光谱（FTIR）确定了关键的振动基团：Te₃、Te₄、BO₃ 和 BO₄。TeO₄ 单元的形成提高了玻璃的辐射屏蔽能力，特别是在 TBZG5 中，由于大 Gd³⁺ 离子和孤对电子的存在，TBZG5 显示出卓越的光子吸收能力。具体来说，掺杂 Gd₂O₃ NP 的玻璃表现出反向可饱和吸收和自聚焦行为，非线性吸收系数范围为 0.660 至 0.729 cm/GW。这些玻璃还显示出非线性折射率不断上升，而整体折射率却不断下降。

Enhanced chemical stability and reduced glass transition temperature are surely desirable for the low-melting sealing glasses. An elusive trade-off between the glass transition temperature and chemical durability in the phosphate glass systems, however, greatly limits the applications of low-melting sealing glasses. In this work, the co-improvements of chemical stability and glass transition temperature are achieved in the xLi₂O-(25-x)Na₂O-17CaO-58P₂O₅ glass system (0 ≤ x ≤ 20 mol%) via a mixed-alkali effect, and this effect on the glasses structures, thermal properties and chemical stability were systematically investigated. The FTIR, Raman and XPS spectra showed that the replacement of Na₂O with Li₂O will enhance and cross-link the glassy network. Particularly, the significantly reduced glass transition temperature (T_g∼331 °C) and softening temperature (T_s∼366 °C) were achieved in the glass with an optimized 10 mol% substitution of Li₂O, demonstrating a great potential of such the mixed-alkali-modulated glasses in the low-temperature sealing applications.

对于低熔点密封玻璃来说，增强化学稳定性和降低玻璃化转变温度无疑是最理想的。然而，磷酸盐玻璃体系在玻璃化转变温度和化学耐久性之间难以权衡，极大地限制了低熔点密封玻璃的应用。本研究通过混合碱效应，在 xLi2O-(25-x)Na2O-17CaO-58P2O5 玻璃体系（0 ≤ x ≤ 20 mol%）中实现了化学稳定性和玻璃化转变温度的共同提高，并系统研究了这种效应对玻璃结构、热性能和化学稳定性的影响。傅立叶变换红外光谱、拉曼光谱和 XPS 光谱显示，用 Li2O 替代 Na2O 会增强和交联玻璃网络。尤其是在 Li2O 取代量为 10 mol% 的优化玻璃中，玻璃转变温度（Tg∼331 °C）和软化温度（Ts∼366 °C）明显降低，显示了这种混合碱调制玻璃在低温密封应用中的巨大潜力。

CuCl₂ substituted bismuth borate tellurite glasses were examined for electrical conductivity at frequencies between 10⁻¹ Hz and 10⁶ Hz and temperatures between 463 K and 563K. The Almond West law used for fitting experimental data of ac conductivity, and determining cross-over frequency (ω_H), frequency exponent (s), and dc conductivity (σ_dc). Depending on the glass composition, ac conduction process was modeled using correlated barrier hopping and non-overlapping small polaron tunneling. The imaginary component of the electric modulus included in the experimental data fitted by non-exponential Kohlrausch-Williams-Watts. Impedance examination reveals minimization of mixed former effect on electric charge transport at low frequencies in studies glasses. For x = 20, conduction occurs due to charge carriers (Cu²⁺ ions/polarons). An excellent match is found between the Nyquist plots and equivalent circuit models. There is good agreement between the estimated activation energy from conductivity E_C (0.82–1.13 eV), electric modulus E_R (0.81–1.12 eV), and impedance E_Z (0.82–1.15 eV) analyses.

对 CuCl2 取代的铋硼酸盐碲玻璃在 10-1 Hz 至 106 Hz 频率和 463 K 至 563 K 温度范围内的导电性进行了研究。阿尔蒙德-韦斯特定律用于拟合交流电导率的实验数据，并确定交叉频率 (ωH)、频率指数 (s) 和直流电导率 (σdc)。根据玻璃成分的不同，利用相关势垒跳变和非重叠小极子隧道来模拟交流传导过程。实验数据中包含的电模量虚分量由非指数 Kohlrausch-Williams-Watts 拟合。阻抗检查显示，在研究玻璃中，混合前效应对低频电荷传输的影响最小。当 x = 20 时，传导是由电荷载流子（Cu2+ 离子/极子）引起的。奈奎斯特图和等效电路模型之间的匹配非常好。电导率 EC（0.82-1.13 eV）、电模量 ER（0.81-1.12 eV）和阻抗 EZ（0.82-1.15 eV）分析得出的估计活化能之间存在良好的一致性。

Basalt fiber is a high-performance fiber made from natural basalt ore by high-temperature melting and filament-forming. The viscosity of basalt melt plays crucial role in regulating melting process and enhancing properties of formed fiber. Here, a dataset of oxide composition in basalt, temperature, and corresponding melt viscosity was collected from reported papers and self-tested samples. By using data-driven and interpretable machine learning technique, two models of Random Forest and Gradient Boosting Decision Tree were established. Both models could learn the dataset and predicted the melt viscosity from the input oxide composition and temperature. A Shapley additive interpretation was conducted on built models, which led to an understanding of significance and pattern of various oxide compositions that impact viscosity. Based on these findings, a prediction on temperature parameters for ore melting and filament-forming was achieved, and continuous basalt fibers were obtained on a fiber spinning facility by using self-tested samples.

A novel sol-gel strategy for the preparation of silica nanocomposites, containing gold nanoparticles (AuNPs), Au(I)-thiolate complexes (Au-SC12) or both disperse phases is demonstrated. The color of the species depends on the size and surrounding of the AuNPs. The nanocomposites obtained are characterized with UV/Vis reflectance spectroscopy, X-Ray diffraction, TEM / EDAX and thermal conductivity measurements. An analysis of the UV/VIS spectra, based on Mie's theory, suggests the presence of 5 - 30 nm AuNPs with different chemical surroundings. Heating of the nanocomposites at 700 °C leads to red or violet colored SiO₂:AuNPs powders. The thermal conductivity of the nanocomposites is about 0.05–0.07 W/m.K, depending on sintering and chemical composition. A discussion about the microstructure of the composites is also presented.

Recently, photoluminescence tomography based on the confocal laser scanning microscopy with two-photon excitation has been developed to study the distribution of point and extended defects in the bulk of ZnSe laser crystals. This article presents the use of the tomography to investigate luminescent micro inclusions in transparent amorphous media such as silicate glass. Studies of CdZnSSe crystals synthesized in a silicate glass melt have been carried out using the tomography with both two-photon and single-photon excitation of luminescence. Zn-rich glass manufactured in the 19th century has been found to contain micron-sized crystals of Cd

) of hexagonal crystal system exhibiting intense photoluminescence. The photoluminescence band of these crystals has been found to peak at about 2.1 eV (

) at 300 K. Minor shifts in the maximum of bands and changes in their shape in individual crystals or at tomogram points within the crystal are associated with variations in their composition. Changes in the photoluminescence band shape and maximum due to the excitation of luminescence in CdZnSSe crystallites by laser radiation of different energies have also been observed in this study.

最近，基于双光子激发共焦激光扫描显微镜的光致发光层析技术被开发出来，用于研究 ZnSe 激光晶体块体中点状和扩展缺陷的分布。本文介绍了如何利用层析技术来研究透明非晶介质（如硅酸盐玻璃）中的发光微夹杂物。我们利用层析成像技术，通过双光子和单光子激发发光，对在硅酸盐玻璃熔体中合成的 CdZnSSe 晶体进行了研究。在 19 世纪制造的富锌玻璃中发现了微米大小的 CdξZn1-ξSζSe1-ζ （ξ≈0.5，ζ≈0.5）六方晶系晶体，这些晶体显示出强烈的光致发光。这些晶体的光致发光带在 300 K 时达到约 2.1 eV 的峰值（∼590 纳米）。晶体内单个晶体或层析点的光致发光带最大值的微小移动及其形状的变化与晶体成分的变化有关。本研究还观察到不同能量的激光辐射在 CdZnSSe 晶体中激发发光所导致的光致发光带形状和最大值的变化。
