초록

육방정계 구조를 가지는 수산화아파타이트 결정은 킬레이트 착화합물을 형성 할 수 있는 EDTA(ethylene diamine tetraacetic acid)를 이용하여 수열조건에서 합성 하였다. 제조된 분말은 X-선 회절 패턴 및 주사전자현미경에 의해 특성 평가 하였다. 제조된 수산화아파타이트 분말은 육방정계 구조의 c축에 따라 결정이 성장하였고, 결정의 형상은 수열온도, pH, EDTA/Ca 및 출발물질의 Ca/P 몰 비와 같은 반응 파라메타에 의해 제어 되었다.

Hydroxyapatite (HAP) crystals with hexagonal structure have been successfully synthesized by using EDTA(ethylene diamine tetraacetic acid) as chelate under hydrothermal condition. The as-prepared HAp powders were characterized by XRD and SEM. The XRD result indicated that the products were preferentially oriented along c-axis. The SEM photographs showed that the morphology of the HAp crystals was well controlled by the reaction parameters such as temperature, pH value, and the molar ratio of EDTA/Ca.
