Abstract
The present invention relates to a sintered ceramic composite implant material and a fabrication method thereof. A sintered ceramic composite implant material includes an apatite matrix phase, a ceramic secondary phase located in the apatite matrix phase, a barrier layer coating the ceramic secondary phase. The secondary phase compensates for and improves the mechanical properties of the apatite matrix phase and the barrier layer restrains an interfacial reaction between the apatite matrix phase and the secondary phase.
