摘　　要：研究了TiO2 、Fe2 O3及CeO2 作为添加剂对烧成镁钙砖烧结性的影响 ,发现它们在一定程度上促进了镁钙砖的烧结 ,其中以TiO2 作为添加剂的效果最好。添加TiO2 、Fe2 O3与CaO反应生成了CaTiO3和Ca2 Fe2 O5,添加CeO2 与CaO不生成化合物。The effect of TiO 2,Fe 2O 3 and CeO 2 as additives on the sintering of fired magnesia calcium brick are investigated.The results indicate that all three kinds of additives can promote sintering of magnesia calcium brick,with the leading of TiO 2.TiO 2 or Fe 2O 3 can react with CaO to get CaTiO 3 or Ca 2Fe 2O 5.CeO 2 can not react with CaO.The mechanisms of three kinds of additives on the sintering of fired magnesia calcium brick are different.
