Fabrication of Hydroxyapatite Whiskers by Hydrolysis of α-TCP

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.

Key words: Hydroxyapatite whisker, Hydrolysis reaction, $\alpha$-tricalcium phosphate
