摘　　要：介绍了水泥回转窑用耐火材料的发展历程以及国内外镁钙锆质耐火材料的研究现状,指出MgO-CaO-ZrO2复相材料既具有镁质材料的优点,矿物相组成中又包含一定数量的钙硅酸盐相,从而具有良好的抗热震性、较高的荷重软化温度及优异的抗硅酸盐水泥熟料的侵蚀性能、适宜的力学强度等,具有较高的实用价值。The development process of cement rotary kiln refractories in cement rotary kiln and the research status of MgO-CaO-ZrO2 refractories in home and abroad were introduced.The MgO-CaO-ZrO2 composite material had advantages of magnesia materials,and its mineral composition contained a certain amount calcium silicate phase.Thus,it had a good thermal shock resistance,a high softening temperature under load,an excellent erosion resistance and suitable mechanical properties,which had important significance and high practical value.
