摘要

玻璃结晶机制在玻璃陶瓷的制备中起着至关重要的作用:它影响相组成和微观结构,从而影响最终产品的性能。在寻找新的玻璃陶瓷材料的过程中,制定适当的热处理计划涉及使用大量需要热处理的玻璃样品,然后进行研究以确定目标特性的值。在本研究中,我们评估了在含有TiO2和ZrO2作为成核剂的ZnO-MgO-Al2O3-SiO2体系中,结晶温度对玻璃陶瓷的玻璃结构、相组成和硬度的影响。为了最大限度地增加热处理次数,我们借助梯度炉在宽温度范围内对玻璃进行了多热结晶。使用X射线衍射、拉曼光谱和透射电子显微镜,我们显示了在单个玻璃样品的主体中作为主要相的钙石纳米晶体的沉淀,并观察到其微观结构、透明度和硬度的逐渐变化。维氏硬度值对热处理温度的依赖性呈非线性趋势,揭示了玻璃结晶的最佳热范围。

One-Step Crystallization of Gahnite Glass-Ceramics in a Wide Thermal Gradient
The glass crystallization regime plays a crucial role in the fabrication of glass ceramics: it affects both phase composition and microstructure, and thus the properties of the final product. In the search for new glass-ceramic materials, the development of a proper heat-treatment schedule involves the utilization of numerous glass samples that need to be thermally treated and then investigated to determine the values of the target characteristics. In this study, we evaluated the effect of crystallization temperature on the glass structure, phase composition, and hardness of glass ceramics in the ZnO-MgO-Al2O3-SiO2 system containing TiO2 and ZrO2 as nucleators. To maximize the number of heat treatments, we performed polythermal crystallization of the glass in a wide temperature range with the help of a gradient furnace. Using X-ray diffraction, Raman spectroscopy, and transmission electron microscopy, we showed the precipitation of gahnite nanocrystals as the main phase in the bulk of a single glass sample and observed a gradual change in its microstructure, transparency, and hardness. The dependence of Vickers hardness values on heat treatment temperature was found to follow a non-linear trend, revealing the optimal thermal range for glass crystallization.
