The mixed powder was calcined at high temperature, and β-tricalcium phosphate(β-TCP) was prepared. 混合粉体高温煅烧处理后制得β-磷酸三钙(β-TCP)粉体。
Evaluation of Technology for Production of Calcined Defluorinated Phosphate in Russia and 俄罗斯与我国烧结法制脱氟磷酸钙的技术评价
The crystal phases and the DTA curves of the catalysts calcined at different temperatures were different from that of the lithium phosphate agent and the DTA curves of the deactivated catalyst were also different; 催化剂使用前后晶型不发生变化,在不同温度煅烧所得的晶型及差热曲线与试剂磷酸锂不同,与失活催化剂DTA曲线差别也很明显;
