The thermal stability of calcium hydroxyapatites (CaHAp) as prepared by traditional methods is quite low, with the preponderance of CaHAp being converted to Ca 3 (PO 4 ) 2 at temperatures as low as 973 K. In contrast, control of the pH during preparation markedly enhances the thermal stability of Ca
