Synthesis and characterization of hydroxyapatite

Jena, Preetam (2007) Synthesis and characterization of hydroxyapatite. BTech thesis.



The current work deals with the synthesis and the subsequent characterization of HAP. The characterization involves analysis of X-ray diffraction, Scanning Electron Microscope, Particle size measurement, Thermogravimetric Analysis (TGA), Sintering and Pressing. In my project I have prepared HAP by the chemical precipitation method.. There was also an experiment undertaken in order to ascertain if there is any change in pH by changing the stages of pH correction XRD patterns were studied of calcined and pre calcined HAP powders. Then the HAP produced was divided into 36 diff 0.8 g batches which were sintered in 3 batches at 1000 0 C, 1100 0 C & 1200 0 C amd then their respective densities were studied. From all the studies made we found out that there is an improvement in crystallinity of HA after calcination. Thermal stability is only upto 1300C.
