摘要
运用XRD、DTA和SEM等分析测试技术,对以TiO2和ZrO2为晶核剂的微晶玻璃的热处理制度与力学性能之间的关系进行了研究。讨论了热处理制度、晶相类型与微晶玻璃力学性能之间的变化关系,得到了最佳热处理工艺,该材料在850℃保温2h,1200℃保温2h以上,弯曲强度可以达到350Mpa左右。
The relationships between heat treatment methods and mechanical properties of micro- crystal glass containing TiO2 and ZrO2 as nucleating agents are studied by using XRD, DTA and SEM. The changing relationships between heat treatment methods, types of crystal phases and mechanical properties of micro- crystal glass are discussed in the paper. And the best heat treatment method is found. The flexural strength of the glassceramics can reach at about 350Mpa when it is heated at 850℃ for 2 hours and then at 1200℃ for 2 hours.
