Abstract

The various methods of preparation for the porous hydroxyapatite ceramics using naphthalene, $H_20_2$ and chlorinated paraffine with $H_20_2$ were investigated. And then the prepared orous hydroxyapatite ceramics were characterized by XRD, SEM, FT-IR and the apparent porosity. The pore size of porous hydroxyapatite ceramics was controlled by the content and size of naphthalene granular. It was found that the porosity of it was increased with the amount of naphthalene, but the bending strength was decreased. The application of hydrogen peroxide produced porous materials like a sponge tissue, but the porosity and the shape of sintered body were hardly controlled. In the case of using chlorinated paraffine with the simultaneous addition of hydrogen peroxide, the sponge tissue was obtained and also could be controlled from 50 up to about 65% porosity of it.

분말상의 유기물인 나프탈렌, 파라핀 및 과산화수소 그리고 과산화수소와 함께 염화파라핀을 사용하여 hydroxyapatite 다공체를 제조하고, 그 특성을 검토하였다. 나프탈렌 분말 입자의 양과 크기에 따라 다공체 기공의 크기와 제어가 가능했다. 또한 나프탈렌의 함량이 많아짐에 따라 기공률은 증가하지만 강도는 상대적으로 감소하였다. $H_20_2$를 사용한 경우에는 해면상의 다공체를 얻을 수 있었지만, 기공률 및 성형체의 모양을 제어하기가 어려웠다. 염화파라핀 $H_20_2$를 함께 사용한 경우, 해면상의 다공체는 물론 50% 이상의 높은 기공률의 제어가 가능하였다.
