摘　　要：研究了在水泥生料中添加不同稀土氧化物对水泥生料的易烧性、硅酸盐水泥熟料的矿物形成和岩相结构的影响。研究结果表明,稀土在适宜掺量条件下能改善生料的易烧性;添加稀土能稳定地促进熟料中A矿的形成,特别是La2O3-CeO2混合稀土氧化物能明显促进A矿的生长发育,并对矿物结晶形态、尺寸和分布都有明显的改善作用。The influences of adding the rare earth oxide in the cement raw meal on the sinterability of the raw meal, mineral formation and petrographic structure of the cement clinker were studied in this paper. The results show that the sinterability of the raw meal was improved by adding appropriate amount of the rare earth. Adding the rare earth will stably promote the formation of Alite in clinker. Especially, La2O3-CeO2 mixed rare earth oxide is capable of accelerating growth of Alite,and improving crystal conformation, size and distribution of the minerals.
