Bonelike apatite fromation on calcium phosphate invert glass-ceramics

Abstract

Bonelike apatite-forming ability on 60CaO-30P₂O₅-3TiO₂-7Na₂O (mol %) glass-ceramics autoclaved at 100∼180°C for 1 h was examined in simulated body fluid (SBF) at 37°C. The autoclaved glass-ceramics formed the apatite on the surfaces within 10 days, while the as-prepared sample (without autoclaving) did not form it. The glassy phase around their surface in the glass-ceramics was suggested to be modified by the autoclaving. The ability of the glass-ceramics was found to be easily improved using the autoclaving treatment.
