Conditions for hydroxyapatite (HAP) synthesis in aqueous solutions by hydrolysis of α-Са3(РО4)2 were studied. Temperature exerts a substantial effect on the rate of α-Ca3(PO4)2 hydrolysis and also changes the morphology of the reaction products. At 40 °C, the plate-like intersecting (perpendicular to the surface of the initial particles) crystals of HAP grow. Their maximum size after the 24-h hydrolysis is 1—2 µm. Needle-like HAP crystals are formed upon boiling of the suspension. The morphology observed for the HAP particles agrees well with the conclusions obtained by analysis of the kinetics of tricalcium phosphate hydrolysis.
