Abstract

Well developed hydroxyapatite whiskers (length 5 ${\mu}{\textrm}{m}$, diameter 0.5 ${\mu}{\textrm}{m}$) have been synthesized by the hydrolysis reaction of $\alpha$-tricalcium phosphate ($\alpha$-Ca$_3$(PO$_4$)$_2$) under pH 9.1 at 9$0^{\circ}C$ for 6 h. The effect of reaction conditions (temperature, time, pH) on the conversion of $\alpha$-tricalcium phosphate to hydroxyapatite was examined. In addition, the hydroryapatite was characterized in terms of microstructure, composition and thermal stability using XRD, SEM, ICP, and TGA instruments.

pH 9.1, 9$0^{\circ}C$, 6시간의 조건에서 $\alpha$-tricalcium phosphate ($\alpha$-Ca$_3$(PO$_4$)$_2$)의 가수분해반응에 의해서 잘 발달된 수산화아파타이트 휘스커상 (길이 5$mu extrm{m}$,지름 0.5$\mu\textrm{m}$)이 합성되었다 수산화아파타이트로 $\alpha$-Ca$_3$(PO$_4$)$_2$의 전환에 미치는 반응조건(온도, 시간, pH)의 영향이 조사되었다. 아울러 XRD, SEM, ICP, TGA와 같은 분석기기를 사용하여 수산화아파트의 미세구조, 조성, 열적 안정성을 검토하였다.
