Hydroxylapatite (HA) is an important part of mineral bone. Synthetic HA is widelyknown as a substitute material for decayed teeth and damaged bones. This is due to its biocompatability with bone material. We chose to investigate wet precipitation reaction as it synthesises a relatively large amount of HA, resulting in a cheaper cost compared to other techniques such as thermal preparation. Moreover, the reaction does not involve foreign materials, and produces a safe by-product, water. Other methods of synthesis exist such as reverse microemulsion, a technique which involves the use and production of harmful organic compounds. As such, we chose to focus our research on the effect of heat on HA synthesised by wet precipitation. This is to determine if a more biocompatible sample of HA can be obtained with application of heat. The synthesised HA powder was characterised by Fourier Transform Infrared Spectroscopy (FTIR), Electron Dispersive X-Ray (EDX), Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD).
