Tertiary calcium phosphate/zirconia bioceramic and preparation method thereof
The invention discloses a tertiary calcium phosphate/zirconia bioceramic and a preparation method thereof, and relates to the field of biomaterials. The bioceramic is prepared from the following ingredients in parts by weight: 40-60 parts of tertiary calcium phosphate, 20-40 parts of zirconia, 5-15 parts of calcium silicate, 3-6 parts of nano titanium oxide, 3-6 parts of medical stone powder, 4-9 parts of potassium metaphosphate and 2-5 parts of nano tungsten oxide. The preparation method comprises the following steps: (1) weighing; (2) ball milling; (3) cold press molding; (4) high-temperature calcining; (5) cooling. The bioceramic is better in biocompatibility and higher in biological activity, meanwhile has excellent compressive strength and fracture tenacity, and is an ideal bone renovating and substitute material.
