Preparation of Hydroxyapatite Powders via Neutralization Process

Abstract:

Hydroxyapatite (HA) and Hydroxyapatite/Chitosan (HA/CS) composite were prepared through neutralization method. The results indicate that the way of adding phosphorous acid solution is a key factor to obtain pure HA product, and that prolonged stirring time only promote the entry of CO₃^2- into the lattice of HA crystal. The addition of chitosan can overcome those factors which hamper the formation of pure HA particles, thus optimizing the whole reaction system.
