Abstract

Nanosized beta-ZnTCP powders with different Zn contents were prepared through coprecipitation of ACP out of the CaCl2-ZnCl2-Na3PO4-PEG system, and calcination of the ACP precursor at 800 degrees C for 3 h. The characterizations of the products showed that the products belong to beta-TCP phase, and the particles sizes of them are about 300 nm, smaller than that of beta-TCP (500 nm). Both the Zn2p binding energy and lattice parameter variations of beta-TCP evidenced that Zn had substituted for Ca in the lattice. Such nanosized beta-ZnTCP powders could be used as bone repair materials with desired and sustained release of Zn.
