Abstract

In this study,calcium carbonate and calcium hydrogen phosphate powders were reacted via a solid state reaction to produce a porous tricalcium phosphate (Ca3 (PO4)2) sample.Then specimens with pellet shape had been produce through a pressing process at 45Mpa at 15seconds.The pellet shape specimen then underwent a drying process at 100⁰C using a drying oven.The sample were sintered at five different temperatures,which were 1075⁰C,1125⁰C, 1175⁰C,1225⁰C and 1250⁰C for 2 hours at heating rate of 10⁰C/min to determine the optimum sintering temperature to produce porous tricalcium phosphate.Besides that,the effect of sintering temperature on the amount of porosity in the porous tricalcium phosphate had been decided.The sintered specimens had been analyzed by characterization techniques such as X-Ray Diffraction (XRD),porosity test and compression test.The morphological analysis was done by using Scanning Electron Microscopy (SEM).β-phase of TCP give it best performance when it has 40% of porosity. Therefore,β-TCP ceramics with porosity of 43% were obtained at 1125⁰C.It is proven that under parameters adopted in this work,the β-TCP phase formed remains thermally stable up to 1175⁰C with an accompanying porosity up to 40%.
