Tertiary calcium phosphate/zirconia bioceramic and preparation method thereof

Abstract

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.

Description

technical field

[0001] The invention belongs to the field of biological materials, in particular to a tricalcium phosphate / zirconia bioceramic and a preparation method of the bioceramic. Background technique

[0002] With the development of material science and technology, biomaterials have become one of the important research directions in the field of biomedicine because of their special properties of repairing, replacing and regenerating body tissues. Biological hard tissue substitute materials were first used body bones and animal bones, and later developed to use stainless steel and plastics. Due to the problems of dissolution, corrosion and fatigue of stainless steel, plastics have problems of poor stability and low strength. Therefore, the bottleneck in the development of biomaterials is caused. The emergence of bioceramics has improved the shortage of existing alternative materials. Because of its many advantages, bioceramics has broad development prospects. [0003...
