Abstract

Highly surfaced and porous hydroxyapatite body was artificially formed on the surface of a shell through a reaction with phosphatic solutions. As a result of qualitative observation, hydroxyapatite seemed to be crystallized by solution-precipitation process accelerated by the nucleation surface of a shell. The process of formation of hydroxyapatite layer was as follows. 1. Dense nucleation and growth on the surface of solid phase 2. Formation of microporous layer by contact and entanglement between crystallines 3. diffusion of solution through the porous layer and thickness growth of layer towards inside

인산염 용액과의 반응으로 패각의 표면에 고 비표면적의 다공성 수산화아파타이트 층이 생성되는 거동을 정성적으로 관찰하였다. 수산화아파타이트의 생성기구는 패각 표면을 핵으로하는 용해-석출 반응으로 보이며 층의 생성은 다음의 과정에 의하였다. 1. 고상 표면 상의 고밀도 핵생성 및 성장 2. 결정의 접촉과 엉킴에 의한 미세 다공성 층의 형성 3. 층을 통한 용액의 확산과 내측으로의 층 두께의 성장
