Abstract
Carbonated barium hydroxyapatite (Ba10(PO4)6(OH)2-2x(CO3)x, X = 0.30-0.57, BaHAP) particles with different Ba/P molar ratios were prepared by a wet method. CO2-3 ions were incorporated into OH- sites of a BaHAP lattice during the preparation at high solution pH. The obtained BaHAP particles were well crystallized and showed a high thermostability. On elevating the mixing temperature of H3PO4 and Ba(OH)2 solutions, the mean particle size of BaHAP particles decreased and their specific surface area increased. The amount of CO2 adsorbed irreversibly on BaHAP particles increased with an increase of their Ba/P molar ratio. Copyright 1999 Academic Press.
