Effect of time of microwave activation synthesis on crystallite size of spheroid β Tricalcium Phosphate nanopowders

Βtricalcium phosphate nanopowders was successfully synthesized by the microwave activated co-precipitation in ambient atmospheric method without adding any surfactant. the synthesized were calcined at 900°c to obtain monophasic βtcp. the powder were characterized using x-ray diffraction,fourier transform-infrared spectroscopy (ft-ir),and transmission electron microscopy to study structure and stability of product as synthesized and after calcination at 900°c. the results showed that amourphous calcium phosphates (acp) and calcium deficient hydroxyapatite (cdha) had been synthesized in a rapid way using microwave assisted co precipitation,which was an important processing method introduced to the synthesis of βtcp after calcination at 900°c. the effects of microwave irradiation,time of irradiation on the reaction mechanism were studied. by using microwave as an assisted method for activation the reaction,the powders can be produced faster by employing an improved and efficient heat transfer throughout the volume and to synthesize nanostructured materials. biocompatible βtcp nanopowders were synthesized with controlled particle size,morphology by this way.
