Abstract: Hydroxyapatite is a sort of biological active ceramics as a likable alternative material of denstry and bone.In this paperneutralization and multi－decomposition is used to synthesis HA on thermo－dynamical analysis basisand analyzes the influential factors:temperaturepH valuethe way and the velocity of adding materialsand supersonicetc.The product is analyzed by chemical analysis to determine the CaP ratiosome using XRD to determine the purity of HA.
