The overall objective of this research is to develop and characterize the hydroxyapatite (HA) bioceramics. In order to achieve these objectives, several aims have been develop to keep track the research in line. The projects aims are to synthesis hydroxyapatite (HA) at various temperatures (room temperature and boiling temperature) and to investigate the effect of temperature on hydroxyapatite (HA) powder such as purity, crystalline structure, reacting temperature and morphological characteristic (grain size, grain shape and diffusion between grains). Industrial grade crystalline HA powder has been successfully synthesis using the wet chemical precipitation method. Scanning electron microscope had showed that the synthesis Hydroxyapatite powder consists of fine grain, homogenous and uniform distribution under the influence of reflux temperature of 30˚C and stirring rate of 350 rpm. The crystallites size for HA powders increased from 2.1868nm to 2.3422nm with increasing of the temperature from 800˚C to 1200˚C. It can be concluded that the wet precipitation route for sample S1.3c (reflux temperature: 30˚C, Stirring rate: 350rpm, Sintering temperature: 1200˚C) is the most suitable to synthesis HA powder over all others parameters.
