Calcium Hydroxyapatite [Ca10(PO4)6(OH)2] is the main inorganic constituent of human rigid tissues. It constitentes the major component of bone and enamel. In our present work, hydroxyapatite was synthesized by chemical co- precipitation method with the addition of different concentrations of calcium nitrate tetra hydrate [Ca(NO3)2.4H2O] and phosphoric acid [H3PO4] using micro wave irradiation. Experiments were conducted under controlled environment maintaining required pH, concentration of solution and temperature. The Present report emphasises on the synthesis and characterization of the nano hydroxyapatite. The result of Fourier Transform Infrared Spectroscopy [FTIR] showed the existence of the functional group present in hydroxyapatite. Scanning Electron Microscope [SEM] explains the surface morphology, size and dimensions of hydroxyl apatite. Thermo Gravimetric Analysis and Differential Thermal Analysis [TGA/DTA] analysis confirms that the high thermal stability of hydroxyapatite is due to the variation in concentration and its hardness is maximum.
