Bioactive biphasic ceramic compositions for artificial bone and method for making the same

Abstract

A bioactive biphasic ceramic composition combining apatite and wollastonite is disclosed, in order to solve the defect of apatite ceramic that has poor bioactivity though it is excellent in biocompatibility, which has improved bioactivity, as compared to monophasic ceramics of apatite or wollastonite. The ceramic composition is produced by steps of: providing a composition including powders of apatite of formula Ca10(PO4)6X, in which X is any one of O, (OH)2, CO3, F2 and Cl2, and wollastonite (CaSiO3) in a weight ratio of 5:95 to 90:10, forming the composition into a desired body by press or forming the composition into a porous body, and sintering the formed body.
