摘要:

  要:利用烧结法制备了CaOAl2O3SiO2系粉煤灰微晶玻璃。采用差热分析方法确定了析晶峰温度Tp,研究了其晶析动力学,并利用JMA方程获得的析晶动力学参数k(Tp)制备玻璃热稳定性。采用X射线衍射、电子探针能谱分析方法研究了微晶玻璃中玻璃基体、晶相的组成。研究结果表明:析晶活化能Ea591.5 kJ/mol,指前因子A1.87 × 1013 min1k(Tp)判据表明玻璃的稳定性随升温速率的增加而降低;升温速率对主晶相的种类没有影响,即均为单一的β-硅灰石,其尺寸大小约为220 μm;基体玻璃中原子种类十分复杂,既有网络形成体,又有网络修饰体和网络中间体,其性质与Na2O?SiO2玻璃相近。

Abstract: A glass-ceramic of CaOAl2O3SiO2 was prepared from coal fly-ash by a sintering method. The crystallization peak temperature Tp was calculated by differential thermal analysis, the crystallization kinetic was investigated, and the thermal stability of glass was estimated by the crystallization kinetic. The crystalline phase and matrix of the glass-ceramic were characterized by X-ray diffraction and electron probe microanalysisenergy spectrum analysis, respectively. The results show that the activation energy Ea is 591.5 kJ/mol, and the index A is 1.87 × 1013 min1. According to the k(Tp), the stability of the glass decreased with increasing the heating rate, and the heating rate had little effect on the major crystalline phases. The β-wollastonite was the single crystalline phase with the grain sizes of 220 μm. The atoms in the glass matrix, which involved the network former, the modified cation and the intermediate former as well, were rather complicated. The property of the matrix was similar to that of the glass of Na2O?SiO2.
