| 摘 要： | 以硼泥为主要原料制备微晶玻璃，通过DTA, XRD, SEM等分析方法，对CaO-MgO-Al2O3-SiO2系玻璃的析晶性能进行研究，系统地分析了烧结时间和晶化时间对微晶玻璃结构的影响. 结果表明其主晶相为钙铁辉石，次晶相为尖晶石和橄榄石，晶粒的尺寸约为2~5 μm；其集合体呈枝晶、柱状晶体和块状晶体；在780℃下的最佳烧结时间为4 h，最佳晶化时间为4 h.

| Abstract: | Glass-ceramic was prepared from raw materials mainly containing boron mud, and the crystallizability of glass ceramic of CaO-MgO-Al2O3-SiO2 system was studied by means of DTA, XRD and SEM. Effects of sintering time and crystallizing time on the microstructure of glass ceramic were also analyzed. The results show that the main crystalline phase of the glass ceramic is hedenbergite, while the subordinate crystalline phases are spinel and olivine, its grain sizes are about 2~5 mm, with dendrite, columnar crystal and bulk crystal existing in aggregation, and the optimum sintering time and crystallizing time are 4 and 4 h, respectively. |
