摘要：

It is possible to prepare calcium hydroxyapatite by reaction of phosphoric acid with calcium hydroxide or calcium carbonate. The physico-chemical study of the precipitate shows that the first method with calcium hydroxide, at room temperature, forms after heating at 900 degrees C an apatite mixed with tricalcium phosphate. The second reaction, with calcite, forms at the beginning a mixture of apatite and calcite which goes through a B-type carbonated apatite and finally forms an hydroxyapatite after a long maturation under constant stirring in a nitrogen atmosphere.
