Abstract: Hydroxyapatite (HAp) is a mineral which is the main composition of bone and teeth in human body. It is well documented that the biocompatibility and bioactivity of bone or teeth could be improved through the synthesis of nanoparticle HAp. Among several methodologies available for synthesizing HAp wet chemical technique was found to be used for well controlling varying processing parameters. This article focuses on synthesis of HAp for surface modification of orthopedic and dental implants. HAp was synthesized using DiAmmonium Hydrogen Phosphate (DHP) and Calcium Nitrate Tetrahydrate (CNT) precursors. Proper care has been taken to maintain pH around 10.8 while stirring with the help of Ammonium Hydroxide (AH). The morphological analysis by Scanning Electron Microscope (SEM) measurement shows that the particles are tightly agglomerated with an average size of 300-400 nm. X-Ray Diffractometry (XRD) analysis detects the purity of HAp. Energy Dispersive X-Ray Spectroscopy (EDX) gives the elemental composition of HAp and further characterization through Fourier Transformed Infrared Spectroscopy (FTIR) was also done
