摘　　要：本工艺以Ca(OH)_2-CaCO_3-H_3PO_4为原料,按中和法原理,采用不同于常规的反应温度和加料操作,制备出反应生成沉淀物不经陈化,易于过滤分离的含CO_3^(2-)的羟基磷灰石(HA)。Based on the principle of neuralization method, carbonate - containing HA has been Prepared at a reaction temperature and addition manipulation of the reactant different from the routine conditions in the system of Ca (OH)2, Ca-CO3 and H3PO4. In this processing, the resulting precipitate requires no ageing time and has a good filterability.
