%X In this paper, synthesised nanometre sized hydroxyapatite (nano-HAP) powders composed of spherical 30 ¡À 5 nm particles were compacted and sintered at temperatures ranging from 650 to 1250¡æ to form ceramics of varying porosity and mechanical strength. The size, crystalline structure and morphology of both the synthesised nano-HAP particle powders and the compacted and sintered ceramics were investigated using both X-ray diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM). Further characterisation techniques such as Brunauer-Emmett-Teller (BET) particle surface area, porosity, bulk density, Vickers hardness and yield strength at various sintering temperatures were tested on sintered pellets and evaluated.
