Hydroxyapatite prepared by a reaction between mortar and phosporic acid

Abstract

Porous hydroxyapatite(HA) prepared on the surface of mortar by a wet process at 40-100°C and pH 10 was characterized with a scanning electron microscope(SEM) and by energy dispersed analysis of X-ray(EDX) and X-ray diffractometry. The appropriate conditions of HA preparation and the formation mechanisms of the HA were briefly discussed.
