Study on the Biocompability of Hydroxyapatite Bioceramics(I) Bonding between Hydroxyapatite Bioceramics in Simulated Body Fluid
Hydroxyapatite powders were synthesized with Ca/P=1.67, 1.70 and pH=7, 11 by precipitation method and fluorine substituted hydroxyapatite ceramics were prepared using these powders. After characterization of these hydorxyapatite bioceramics, chemical bonding between these sepcimens in simulated body fluid was investigated. Bysubstitution of 7.5% of fluorine, hydroxyapatite was prevented to decompose into β-tricalcium phosphate and its sintered density and mechanical strength were increased. The bending strength of these hydroxyapatite ceramics was 137MPa. The hydroxyapatite ceramics chemically bonded each other in Ringer's solution and the component of bonded layer was also hydroxyapatite.
