利用拜耳法赤泥制备烧胀陶粒的研究 王林江1,赵建新1,谢襄漓1 (1.桂林工学院材料与化学工程系新材料及其制备新技术广西重点实验室,广西,桂林,541004) 摘要:以拜耳法赤泥为主要原料,通过掺加废玻璃,粉煤灰等固体废弃物,再加入少量的添加剂制备烧胀陶粒.结果表明,赤泥的掺加量和焙烧温度是影响陶粒的物理性能和显微结构的主要影响因素.当赤泥的掺加量为50%,焙烧温度为1140℃时,可得到外表面玻璃化程度良好,内部孔隙比较均匀,以封闭孔为主的陶粒.该陶粒的主要成分为赤铁矿,水钙铝榴石,钙长石,钙钛矿,霞石和玻璃体.陶粒的颗粒抗压强度为0.6kN,吸水率为0.4%,表观密度为1.31g/cm3. 关键词:赤泥; 烧胀陶粒; 吸水率; 表观密度; Red mud; Sintering-expanded haydite; Water absorption; Apparent......
