Enhancement of Bone-Like Apatite Forming Abilities of Calcium Phosphate Ceramics in SBF by Autoclaving

Abstract

Bone-like hydroxyapatite (b-HA) formation abilities of β-tricalcium phosphate (β-TCP) and hydroxyapatite (HA) after autoclaving were evaluated by immersion tests using simulated body fluid (SBF). The b-HA formation was observed on an autoclaved β-TCP, while no deposition was observed on the non-autoclaved one. The b-HA formation on HA was observed to be enhanced after autoclaving. Decrease of surface potentials by autoclaving may enhance the b-HA formation abilities.
