23 Jul Beta-tricalcium phosphate (TCP)/calcium carbonate (CC) double-phase ceramic material and preparation method thereof
Abstract
The invention discloses a beta-tricalcium phosphate (TCP)/calcium carbonate (CC) double-phase ceramic material and a preparation method thereof and belongs to the field of biological materials. The beta-tricalcium phosphate/calcium carbonate double-phase ceramic material is prepared from the following components in percentage by weight: 10wt%-85wt% of beta-tricalcium phosphate, 10wt%-85wt% of calcium carbonate and 5wt%-30wt% of a phosphate glass additive. With the adoption of a beta-TCP/CC double-phase ceramic system prepared by the invention, the early osteogenic activity of artificial bones can be improved, and the problem that the degradation speed of an artificial bone material is not matched with a bone growing speed can also be solved; and the requirements of bone defect repairing and bone tissue engineering are met. The material has good biocompatibility, introduction of the osteogenic activity and full-biodegradation property and can be used for repairing and replacing bone defects of people; and the composition and structure of the material are adjusted, so that the biodegradation speed of the material can be adjusted and is matched with the growing speed of bone tissues.
