摘要:
由于Al2O3-MgO-CaO系耐火材料在烧成过程中存在许多对烧结致密化不利的因素,进而影响其相关性能的使用. 为此,在1 500~1 600 ℃条件下制备了Al2O3-MgO-CaO复合材料,并研究加入CeO2添加剂对该系耐火材料烧结致密化的影响. 实验结果表明:将CeO2添加到Al2O3-MgO-CaO系耐火材料的较优烧成温度为1 600 ℃,当CeO2的添加量(质量分数,下同)分别为4 %和6 %时,其显气孔率分别降低至3.9 %和3.8 %,体积密度从未添加时的2.88 g/cm3分别升高至3.62 g/cm3和3.68 g/cm3;同时,通过扫描电镜观察发现添加CeO2后该系耐火材料显微结构致密化程度较高,从而实现其良好的致密化.
