ZnO对黄磷炉渣微晶玻璃析晶影响
|
摘要
以黄磷炉渣为主要原料,通过添加不同比例ZnO,采用熔融法制备了CaO-Al_2O_3-SiO_2系微晶玻璃。借助Kissinger方程分析黄磷炉渣基础玻璃的析晶能力,借助化学热力学软件FactSage 6.4模拟计算黄磷炉渣微晶玻璃晶相类型,借助X射线衍射仪(XRD)和扫描电子显微镜(SEM)进行验证。结果表明:随着ZnO添加量的增加,黄磷炉渣基础玻璃的析晶峰温度Tp和析晶活化能E逐渐减小;当ZnO添加量为7wt%时,黄磷炉渣基础玻璃的析晶活化能E最小,析晶能力最强;随着ZnO的加入量的增大,黄磷炉渣微晶玻璃晶相类型并不发生改变,主晶相为硅灰石(CaSiO_3),次晶相为铝透辉石(Ca(Mg,Al)(Si,Al)_2O_6),这与FactSage 6.4模拟计算结果一致。
A series of CaO-Al_2O_3-SiO_2 glass-ceramics were prepared by melting method using yellow phosphorus furnace slag as the main raw material and adding different amount of zinc oxide. The crystallization activation energy was calculated using Kissinger equation. The crystal phase composition was calculated by FactSage 6. 4. The results of simulation and calculation were proved by means of X-ray diffraction and scanning electron microscopy. The results show that temperature of crystallization peak and the crystallization activation energy of basic glass gradually decrease with the increasing of zinc oxide content. When adding 7 wt% zinc oxide,the crystallization activation energy of basic glass is minimum.The predominant crystalline phase is wollastonite(CaSiO_3) and the minor crystalline phases is aluminian diopside(Ca(Mg,Al)(Si,Al)_2O_6) and it doesn't change with the increase of zinc oxide content. It is consistent with FactSage 6. 4 calculation results.
