Abstract：
 The present invention belongs to the field of biomedicine material technology, and is preparation process of composite hydroxyapatite/Ti3SiC2 bioceramic material. Ti3SiC2 and hydroxyapatite in certain ratio are mixed and sintered in non-oxidizing atmosphere or in vacuum state and at high temperature over 1250 deg.c to obtain the composite hydroxyapatite/Ti3SiC2 bioceramic material. The composite hydroxyapatite/Ti3SiC2 bioceramic material has high mechanical performance, including bending or breaking strength 70-300 MPa, toughness of 0.9-8 MPa.m1/2, elastic modulus 100-250 GPa and Vicker hardness 3-6 GPa; excellent machining property and excellent biomedical compatibility.
