摘要：

The thermal conversion of octacalcium phosphate into hydroxyapatite has been investigated by a crystallographic, thermogravimetric, and calorimetric study. The conversion of octacalcium phosphate takes place through the remotion of three of its five water molecules and yields a poor crystalline apatitic phase. The three water molecules are lost in two steps. The first one, which is reversible, corresponds to the remotion of one water molecule and induces a slight contraction of the unit cell of OCP. The successive remotion of two water molecules, which provokes the structural conversion of OCP into apatite, is in irreversible process. The mechanism of the water loss of OCP is explained in terms of its crystal structure. © 1990.
