Notes:
In order to solve the problems on synthesizing carbonated hydroxyapatites (CHA) by theconventional heating precipitation method, such as long reaction and large particle size, poorcrystallinity of CHA etc, the nanosized CHA particles have been synthesized by microwave heatingmethod using phosphoric acid (H3PO4), calcium hydroxide (Ca(OH)2) and calcium carbonate(CaCO3 ) as starting materials in the present paper. The influences of power level and time ofmicrowave irradiation on synthesis of CHA have been investigated. The X-ray diffraction (XRD)analysis has indicated that microwave heating will reduce CHA crystallization time and improvecrystallinity of CHA. Scanning electron microscope (SEM) analysis has showed that CHA particlesare of rod like morphology with about 60nm width and 200nm length respectively. Infraredspectroscopy (IR) analysis has confirmed the B-type CHA precipitate can be formed undermicrowave irradiation. The microwave irradiation plays an important role to promote the reactionand the synthesis of nanosized CHA particles
