Description

technical field [0001] The invention belongs to the field of biomaterials, in particular to a zirconia bioceramic used for manufacturing hip joints 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. ...
