Abstract

The invention discloses a calcium phosphate bioactive ceramic and a preparation method thereof, and relates to the field of biomaterials. The calcium phosphate bioactive ceramic is prepared from the following ingredients in parts by weight: 50-75 parts of tetracalcium phosphate, 3-9 parts of titanium oxide, 3-8 parts of aluminum silicate fiber, 2-5 parts of zinc oxide, 10-22 parts of tertiary calcium phosphate and 6-10 parts of calcium oxide. The preparation method comprises the following steps: (1) weighing; (2) ball milling; (3) cold press molding; (4) high-temperature calcining; (5) cooling. The calcium phosphate bioactive ceramic has certain mechanical stability and better biocompatibility; meanwhile, the calcium phosphate bioactive ceramic can slowly dissolve and release the bone nutrition elements of calcium and phosphorus, promotes bone growth, and is an ideal bone renovating biomaterial.

Description

technical field [0001] The invention belongs to the field of biomaterials, in particular to a calcium phosphate bioactive ceramic 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] Calcium pho...
