Effects of Aging Time and Sintering Temperatures on Thermal, Structural and Morphological Properties of Coralline Hydroxyapatite

Biphasic Calcium Phosphate bioceramics belong to a group of bone substitute biomaterials comprised of an intimate mixture of Hydroxyapatite (HAP) and β-Tricalcium Phosphates. In the present work, Coralline Hydroxyapatite was synthesized using wet precipitation method. Powder particles were aged for 24 and 48 hours at 5. X-Ray Diffraction, Fourier Transform Infrared and Thermogravimetric spectroscopic techniques were used. Biphasic Calcium Phosphate was identified as the chief structural constitution of the synthetic powders. Weight fraction of Hydroxyapatite increased with the rise of sintering temperature. Aging time of 24 hours yielded maximum amount of hydroxyapatite, thus confirming optimum aging time for the synthesis of Coralline Hydroxyapatite
