摘　　要：用不同方法(化学合成法、共沉淀法、振荡法)制备了锌酸钙[Ca(OH)2.2Zn(OH).2H2O]。用XRD、SEM和TG-DTA等方法对其结构、形貌和组成进行了测试和比较。结果表明:不同法方法所制得的锌酸钙的结构、形貌和组成极其相似。但用振荡法制得的锌酸钙,比化学合成法或共沉淀法制得的锌酸钙具有更小的晶粒。Calcium zincates [Ca（OH）2·2Zn（OH）2·2H2O] were prepared by various methods （chemical synthesis, coprecipitation, oscillation）. Their structure, morphology and composition were tested and compared by XRD, SEM and TG-DTA. The experiment results showed that the structure, morphology and composition of calcium zincates made with different methods were extremely similar. But the calcium zincate prepared by oscillating had smaller crystalline grain compared to those prepared by chemical synthesis or coprecipitation.
