| Summary: | Hydroxyapatite (HAp) is a kind of bioceramic based material that has been used extensively in many medical applications. Owing to nearly similar mineral contents to natural bone, the material has been accepted as an implant in order to improve the osteointegration with the bone tissue. In this work, an alternative processing route from waste materials, namely clamshell in producing HAp powder is presented. The effects of processing temperatures, ranging from 750°C to 950°C and pH values, ranging from 6.5 to 8.5 on the synthesized HAp prepared via chemical precipitation method were investigated. From the XRD, FTIR and EDX results, it was observed that the lowest pH value of 6.5 with the temperature of 850°C is the optimum parameters to synthesize HAp. © (2014) Trans Tech Publications, Switzerland.
