Abstract

Chemical bonding was investigated in the simulated body fluid of several selected hydroxyapatite-containing composites. The hydroxyapatite-containing composites chemically bonded with each other in the simulated body fluid after 4 weeks. Bioglass was strongly bonded in the simulated body fluid, but bonding strength was not depended on composition. Their composite bodies were chemically bonded by heterogeneous nucleation and growth at the interfaces of the specimens in the simulated body fluid.

참치 뼈에서 추출한 hydroxyapatite를 출발물질로 여러 가지 세라믹 복합체를 제조하여 인공체액에서의 hydroxyapatite 복합체간의 화학결합을 조사하였다. Hydroxyapatite 복합체들은 인공체액에서 4주 후부터 화학 결합성질을 나타내었다. 결합강도는 bioglass가 가장 강하게 나타났으며, 조성에 따른 의존성은 관찰할 수 없었다. 인공체액에서 복합체들은 이들의 경계면에서 불균일 핵생성 및 성장에 의해 화학적 결합으로 이루어졌다.
