Synthesis of hydrokxyapatite based duck egg shells using precipitation method

Abstract

The need for implants increases with the high number of fracture sufferers resulting from accidents both on the road and workplace accidents. Bioceramics is a ceramic product or component used in the medical and dental industry, especially as an implant or organ replacement. Hydroxyapatite is one type of bioceramics that is widely used because it has osteoconductive properties (can stimulate bone growth), bioactive and biocompatible. This study aims to reduce and add value to the use of duck egg shells waste. This research method consists of three stages, namely: calcination of duck egg shells, HA synthesis with the wise drop precipitation method and Characterization using XRD and SEM to identify the phase, lattice parameters, and crystal size and determine the morphology of the sample which has been synthesized. HAp synthesis was carried out by reacting CaO from duck eggshells with phosphate source (NH4) 2HPO4 using precipitation method at 1000°C sintering temperature for 5 hours and calcination time for 4 hours. Based on the results of the XRD analysis showed the purity of the Hap sample. While the SEM test shows the morphology of the HAp sample.
