| 中文摘要: |
| 探讨了利用白云石和工业磷酸合成磷酸钙磷酸镁复合物的理论依据,分析了影响合成的工艺因素,讨论了钙镁合量与磷的摩尔比(Ca+Mg)/P、磷酸加入速率、合成温度和保温时间对合成的影响。实验结果表明,合成磷酸钙磷酸镁复合物的最佳工艺参数为：钙镁合量与磷的摩尔比(Ca+Mg)/P1.60,磷酸加入速率2 mL/min,合成温度1050℃,保温时间40 min。 |
| 英文摘要: |
| This paper is intended to study the theoretical basis of the use of dolomite and industrial phosphoric acid to synthesize calcium phosphate and magnesium phosphate,analyze the factors influencing the synthesis process,and discuss the influence of the molar ratio of calcium+ mag-nesium and phosphorus(Ca+Mg)/P,phosphoric acid addition rate,synthesis temperature and holding time on the synthesis.The experiment results show the optimum parameters of the syn-thetic process of calcium phosphate and magnesium phosphate:the molar ratio of calcium+ mag-nesium and phosphorus(Ca+Mg)/P is 1.60,the phosphoric acid addition rate is 2 mL/min,the synthesis temperature is 1050 1 050 ℃,and the holding time is 40 min. |
