Fabrication of Hydroxyapatite Whiskers by Hydrolysis of α-TCP

α-TCP의 가수분해에 의한 수산화아파타이트 휘스커의 제조

  • Published : 2003.06.01

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.
