摘要
采用差热分析(DTA),X射线衍射分析(XRD)和扫描电子显微镜(SEM)等分析手段研究了Li2O-Al2O3-SiO2(LAS)系统玻璃的烧结和析晶。通过实验确定了最佳烧结温度,并获得主晶相为β-锂辉石的Li2O-Al2O3-SiO2(LAS)的微晶玻璃。结合烧结体的体积密度、显气孔率和吸水率的数据,分析说明了粘结剂PVA的加入对玻璃粉烧结体性能的影响。
The sintering and crystallization of Li2O-Al2O3-SiO2 （LAS） system glass--ceramics were investigated by differential thermal analysis （DTA）, X--ray diffraction analysis （XRD） and scanning electron microscopy （SEM） and other methods. The optimum sintering temperature was ex- perimentally determined. And Li2O-Al2O3-SiO2 （LAS） glass-- ceramics containing β- spodumene as the main phase were obtained. Combined with the data of bulk density, porosity and water absorp- tion of sintered body, described the effect of the addition of binder PVA on the performance of the glass powder sintered body.
