【摘要】：以粉煤灰和自然冷黄磷炉渣为研究对象,采用熔融法制备CaO-Al_2O_3-SiO_2(CAS)系微晶玻璃。利用Kissinger方程和Augis-Bennett方程计算了粉煤灰-自然冷却黄磷炉渣微晶玻璃玻璃析晶活化能(E)和晶化指数(n)。借助差热分析(DTA),X射线衍射仪(XRD)和扫描电子显微镜(SEM)研究了晶核剂TiO_2,CaF_2,P_2O_5(由KH_2PO_4引入)对粉煤灰-自然冷却黄磷炉渣微晶玻璃析晶的影响。结果表明:利用粉煤灰和自然冷却黄磷炉渣并添加一定量的辅料可以制备CAS系微晶玻璃。当分别添加2wt%的TiO_2,CaF_2,P_2O_5时,主晶相不发生改变,均为硅灰石(CaSiO_3),但添加2wt%TiO_2或2wt%CaF_2具有降低析晶活化能、促进析晶的作用,而添加2wt%P_2O_5具有增加析晶活化能、抑制析晶的作用。
