dc.description.abstractThe golden apple snail shell was mechanically milled to transform to 400 mesh sizes of calcium carbonate CaCO3. The obtained CaCO3 was reacted with phosphoric acid by a simple rapid reaction to prepare dicalcium phosphate hydrate CaHPO4<sup>.</sup>1.9H2O. Thermal transformation products of the as-synthesized CaCO3 and CaHPO4<sup>.</sup>1.9H2O samples occurred at above 750 <sup>o</sup>C indicating the temperature condition to synthesize tricalcium phosphate Ca3(PO4)2 by solid state route. The as-synthesized CaCO3 and CaHPO4 powders were well mixed in the mole ratio of 1:2, then calcined at 800 <sup>o</sup>C for 2 hrs. and the obtained product was Ca3(PO4)2. The XRD and FTIR results indicate that the as-prepared CaCO3, CaHPO4 and Ca3(PO4)2 samples without the presence of any phase impurities crystalize in orthorhombic of aragonite, anorthic, rhombohedral phases respectively, The SEM micrographs show nonuniform, wooden fiber-like, grainy rice-like and irregular and non-uniform shapes for the as-prepared CaCO3, CaHPO4 and Ca3(PO4)2 samples respectively.
