dc.description.abstract Coral sand grains were analysed using simultaneous differential thermogravimetric analysis (DTA/TGA) Fourier-Transform infrared spectroscopy (FTIR), x-ray diffraction (XRD) and environmental scanning electron microscopy (ESEM). These techniques were performed to confirm the characteristics and properties as well as the composition of the coral sand grains. Imaging of the full surface topography were conducted inthe ESEM. After characterisation coral sand grains were treated for impurities and organic materials were subsequently removed. The materials were then converted to calcium phosphates utilising hydrothermal treatment. The results have shown that the coral sand grains were composed of calcium carbonate with a network of uniform inner porous structure. The ESEM has provided valuable information through the imaging of the samples which in turn allowed a comparison of the pore sizes before and after the hydrothermal treatment. The current study shows that the coral sand to be a promising source of converted calcium carbonate to calium phosphates for biomedical applications. en_US
