Synthetic calcium hydroxyapatite, Ca_10(PO_4)_6(OH)_2 (CaHap), prepared by a wet method was evacuated at various temperatures up to 900 C and the influence of thermal treatment on the structure of this material was investigated by FTIR, determination of concentration of surface P-OH groups, adsorption of H_2O and heat of mersion in water. The number of surface P-OH groups was 2.6 groups nm^(-2) and the ionic ratio of surface (PO_4)^(2-) - to H_2PO_4 - was 31: 69. The surface P-OH groups were essentially dehydroxylated by outgassing above 400 C to produce surface P-O-P species. The heat of rehydroxylationper one P-O-P group was determined to be 1.43 x 10^(-16) J group^(-1). When outgassed above 600 C, CaHap was rehydrated via the reaction: ...
