dc.description.abstract	The chemical co-precipitation method has been used for the synthesis of nanocrystalline hydroxyapatite (HAP) powder from Ca(NO3)2.4H20 and (NH4)H2PO4 . The thermal stability of the HAP powder was determined. The phase composition of raw-HAP and calcined product were characterized by XRD. The HAP powder has been sintered into micro-porous ceramic in air at different temperature with different time. Sintering kinetics was investigated by determining bulk density and shrinkage of sintered disc. The microstructure of the resulting HAP was characterized by scanning electron microscope. It may be concluded that Ca/P ratio of HAP is dependant on the pH of the precipitation reaction. Ca-deficient HAP is stable upto 900oC and densification of nanocrystallite HAP is dependant on the time of firing, i.e. decomposition reaction of the HAP.	en
