%X Ultrafine hydroxyapatite (HA) particles were prepared in the emulsion of chloroform and water with lecithin as the emulsifier, and the effect of lecithin on the dispersion of HA particles in chloroform was explored. FTIR and TEM analysis show that lecithin can attach on the surface of HA particles, greatly improves their dispersion in chloroform after demulsification. Therefore, a suspension of nano-sized HA particles with excellent dispersion in organic media can be prepared with this method. When compounded with PMMA, the HA particles can be distribute homogeneously in the PMMA matrix. The results suggest that the suspension is significant to achieve a desirable composite microstructure during the preparation of HA-reinforced composites.
