以温石棉尾矿、石灰石和石英砂为主要原料,通过不同的热处理过程制备了微晶玻璃。借助DTA、XRD及SEM等分析测试手段,研究了核化和晶化温度对微晶玻璃析晶行为、显微形貌及抗压强度的影响。结果表明：随着热处理温度的升高,微晶玻璃主晶相的种类没有改变,但主晶相衍射峰的强度呈现先增强后减小的趋势。当核化温度为820℃,晶化温度为1050℃时,微晶玻璃样品形成致密的柱状细晶结构,抗压强度达到最大值523 MPa。
Glass-ceramics was prepared with chrysotile asbestos tailing,limestone and quartz sand as primary material by different processes.Effects of nucleation temperature and crystallization temperature on crystallization behavior,microstructure and compressive strength of glass-ceramics samples were analyzed by means of DTA,XRD,SEM and other analytical methods.The results show that with the increasing of heat treatment temperature,the species of the main crystalline is the same,but the intensity of XRD peak increase first,and then decrease.The glass-ceramics samples with best properties are obtained by nucleating at 820 ℃ and crystallizing at 1050 ℃.The glass-ceramics sample consisting of small columnar crystals has high compressive strength of 523 MPa.
