The Influence of Conditions on Synthesis Hydroxyapatite By Chemical Precipitation Method

Particles of Hydroxyapatite (HAp) were synthesized by means of chemical precipitation method, under atmosphere pressure. The starting solution with the Ca/P ratio of 1.67 was prepared by mixing 0.167 mol·dm−3 Ca(NO3)2·4H2O, 0.100 mol·dm−3 (NH4)2HPO4, 0.500 mol·dm−3 (NH2)2CO and 0.10 mol·dm−3 HNO3 aq...

Description
Summary:Particles of Hydroxyapatite (HAp) were synthesized by means of chemical precipitation method, under atmosphere pressure. The starting solution with the Ca/P ratio of 1.67 was prepared by mixing 0.167 mol·dm−3 Ca(NO3)2·4H2O, 0.100 mol·dm−3 (NH4)2HPO4, 0.500 mol·dm−3 (NH2)2CO and 0.10 mol·dm−3 HNO3 aqueous solutions. The hydroxyapatite were prepared by heating the solution at 80 °C for 24 hour and then at 90°C for 72 hour. Then followed, the dry powers were heat treatment at 660°C temperatures for 8 hour. The obtained powder was analyzed using XRD, XRF, FT-IR, SEM, TG-DTA. The results showed that obtained HAp powers were greatly influenced by synthetic conditions. HAp powders with various morphologies, such as sphere, rod, layered, dumbbell, fibre, scaly, were obtained by controlling the synthetic conditions.
