Description

Technical field: [0001] The invention relates to the technical field of bioceramic materials, in particular to a porous wear-resistant bioceramic material and a preparation method thereof. Background technique: [0002] Bioceramics refers to new types of ceramics related to living organisms or biochemistry, including fine ceramics, porous ceramics, certain glasses and single crystals. Commonly used bioceramics include alumina ceramics and single crystal alumina, calcium phosphate ceramics, glass-ceramics, zirconia sintered bodies, etc. They are clinically used as artificial teeth, artificial bones, artificial heart valves, artificial blood vessels and other medical Artificial tracheal piercing joints, etc. [0003] Bioceramics also need to have relatively good mechanical properties, such as ideal porosity, hardness, flexibility, compressive strength and bending strength. Currently common bioceramic materials are poor in the above-mentioned various properties, so there is a...
