Abstract

Hydroxyapatite (HAp) particles were synthesized by two processing methods such as solid-state reaction and wet chemical reaction, and were characterized in terms of their chemical composition, disordered structure and in vitro biodegradability. XRD revealed that the prepared HAp particles were composed of single phase HAp, while 1D and 2D solid-state NMR analysis showed that the prepared HAp particles consisted of not only crystalline HAp but also disordered phase. The in vitro biodegradability was discussed by using a structure model for nano-crystalline HAp, in which the nano-crystals consist of a crystalline HAp core covered with a disordered surface layer (core-shell model).
