Abstract

The invention belongs to the field of medical materials and discloses an alumina bioceramics material and a preparation method therefor. The ceramic material is prepared from the ingredients in parts by weight: 16-28 parts of alumina, 3-6 parts of molybdenum boride, 3-5 parts of boron nitride, 2-5 parts of chromium boride, 3-7 parts of tungsten silicide, 4-8 parts of cobalt silicide, 2-4 parts of magnesia, 2-4 parts of copper, 1-3 parts of zirconium, 2-5 parts of rubidium and 1-3 parts of nickel. The preparation method disclosed by the invention comprises the following steps: (1) carrying out mechanical ball-milling on the ingredients (in parts by weight) in a ball mill; (2) after ball-milling, uniformly mixing a mixed cermet material; and (3) carrying out high-temperature sintering on the mixture, which is uniformly mixed in the step (2), in a high-temperature sintering furnace for 3 hours at the temperature of 800 DEG C to 900 DEG C, then, heating the mixture to the temperature of 950 DEG C to 1,050 DEG C, carrying out sintering for 4 hours, and cooling the mixture to room temperature, thereby preparing the alumina bioceramics material.

Description

technical field [0001] The invention belongs to the field of new biological materials, and relates to an alumina bioceramic material and a preparation method thereof. Background technique [0002] With the development of science and technology and the improvement of manufacturing technology, alumina ceramics have been more and more widely used in modern industry and modern science and technology.
