摘要
以六水氯化镁、氢氧化钠和磷酸为基本原料制备八水磷酸镁(Mg_3(PO_4)_2·8H_2O)。其主要条件:温度323K,pH值6.8。八水磷酸镁在435K脱去八个结晶水,得到无水磷酸镁。
Trimagnesium phosphate octahydrate (Mg3(PO4)2· 8H2O) was prepared using magnesium chloride hexahydrate, sodium hydroxide and phosphoric acid as starting materials at T = 323K and pH = 6.8. Anhydrous trimagnesium phosphate was obtained by dehydration of octahydrate at 43 5K.
