摘要：

Precipitation of amorphous calcium phosphate and its transformation into crystalline materials are investigated. The variation in pH during the total process can be explained by initial formation of one amorphous phase, ACP1, followed by formation and growth of another amorphous phase, ACP2, causing dissolution of the initially formed phase. The amorphous phase ACP2 similarly dissolves due to formation and growth of octacalcium phosphate, OCP, which finally dissolves due to formation and growth of deficient hydroxyapatite. Apparent solubility products are determined for ACP1, ACP2 and OCP. From the variation of the solubility products with temperature, H{circled dash} and S{circled dash} for the dissolution of ACP1, ACP2 and OCP are determined. © 1990.
