| 中文摘要 | 本文设计了Na2O-CaO-SiO2-MgO-Al2O3-ZnO体系,采用熔融法制备了以磷渣为主要原料的微晶玻璃,磷渣在微晶玻璃中的使用率达到67～75%,并利用XRD,SEM等确定了玻璃的最佳热处理制度,研究了Na2O对微晶玻璃析晶及特征的影响。结果发现经过750℃核化4h,850℃晶化2h,得到主晶相为硅灰石(CaSiO3)和菱硅钙钠石(Na2Ca2Si3O9)的微晶玻璃。玻璃中表面析晶和整体析晶同时存在,其中Na2O可促进整体析晶和菱硅钙钠石的析出。; The glass-ceramics was prepared from the phosphorus slag as main primary raw materials by melt quenching technique.The optimal heat-treatment schedule of glass-ceramics was determined,and the effects of Na2O on crystallization behavior of glass-ceramics were investigated by X-ray powder diffraction analysis and scanning electron microscopy.It was shown that the glass-ceramics were obtained by nucleation at 750 ℃ for 4 h and crystallization at 850 ℃ for 2 h,which the main crystalline phases are wollastonite and combeite.Na2O promotes volume crystallization and the precipitation of combeite. |
