摘要(Abstract)：

以高钛高炉渣和废玻璃粉为主要原料,采用发泡和析晶同步进行的"一步法"制备泡沫微晶玻璃,研究热处理保温时间对泡沫微晶玻璃的组织与性能影响。结果表明:在1000℃下,随保温时间从30 min延长至60 min,泡沫微晶玻璃中主晶相由斜辉石Ca(Ti,Mg,Al)(Si,Al)2O6转变为钙铁辉石Ca Fe(Si2O6)和普通辉石Ca(Mg,Fe,Al)(Si,Al)2O6,其晶相含量增加且由粒状结构向棒状结构过渡,材料孔径增大,体积密度、导热系数与吸水率逐渐降低,抗压强度升高;保温时间在60~120 min时晶相不发生明显变化,其含量缓慢增加且逐渐融合呈球状结构,材料出现连通孔,体积密度、导热系数与吸水率逐渐升高,抗压强度下降。综合而言,当保温时间为60 min时,所制得的泡沫微晶玻璃具备最优综合性能。
