【摘要】 以山西翼城高炉矿渣为主要原料,采用烧结法制备微晶玻璃.利用差热分析仪(DTA)、扫描式电子显微镜(SEM)、X射线粉末衍射仪(XRD),研究矿渣微晶玻璃的成分、制备工艺,以及对显微结构和性能等进行分析.研究结果表明,当基础玻璃化学组成(质量分数)分别为50%~60%(SiO2),4%~8%(Al2O3),14%~19%(CaO),7%~10%(MgO),0.7%(Fe2O3),4%(Na2O),6%(K2O)时,主晶相为透辉石,高炉渣最大引入量达到47.35%,最小量为28.06%,可以获得性能良好的烧结型微晶玻璃.更多还原

【Abstract】 One kind of sinter glass-ceramics was studied,where slag from Yicheng of Shanxi province was used as main raw materials.Temperature of nucleation and crystallization,the crystal phase and structure of slag glass-ceramics were investigated by DTA,XRD and SEM.Results showed: When slag glass-ceramics′ compositon was: 50%～60%(SiO2),4%～8%(Al2O3),14%～ 19%(CaO),7%～10%(MgO),0.7%(Fe2O3),4%(Na2O),6%(K2O),it′s principal crystal phase was diopside,and the percent of slag add into batch mixture could be 28%~48%.Sinter slag glass-ceramics with uniform and compact structure were prepared,and performance of glass-ceramics were excellent.更多还原
