Abstract

The invention belongs to the field of biological materials and discloses a composite biological ceramic material and a preparation method thereof. The biological ceramic material is prepared from the following components: 12-18 parts of calcium aluminate, 10-16 parts of silicon oxide, 14-20 parts of aluminum phosphate, 10-15 parts of magnesium aluminum silicate, 5-8 parts of calcium oxide, 3-7 parts of zirconium silicate, 6-11 parts of niobium silicide, 5-13 parts of vanadium silicide, 4-9 parts of boron nitride and 6-10 parts of molybdenum boride. The preparation method comprises the following steps: (1) uniformly mixing the materials at a high speed; (2) performing ball-milling through a ball mill; (3) pressing and molding in a hot pressing furnace, heating the hot pressing furnace to 760-800 DEG C and keeping the temperature for one hour, heating to 1230-1430 DEG C and sintering at a high temperature, and cooling to the room temperature, thereby obtaining the composite biological ceramic material.

Description

technical field [0001] The invention belongs to the field of medical biomaterials, and relates to a biomaterial and a preparation method thereof, in particular to a composite bioceramic material and a preparation method thereof. Background technique [0002] Bioceramics refers to new ceramics related to living organisms or biochemistry. Includes fine ceramics, porous ceramics, certain glasses, and single crystals. According to the use, bioceramics can be divided into implant ceramics related to living organisms and biotechnology ceramics related to biochemistry. Implanted ceramics are implanted into the living body to restore and enhance the function of the living body. Since the implanted ceramics are in direct contact with the organism, it is required to have a good affinity with the organism, not to produce toxic erosion and decomposition products; not to cause biological cells to mutate, necrosis, and cause inflammation and growth of granulation; in vivo It has good f...
