Abstract

The invention discloses a wear-resistant ceramic material and a preparation method thereof. The wear-resistant ceramic material is made of the following components by weight: 65-70 parts of nano-alumina, 10-15 parts of magnesium carbonate, and kaolin 10‑12 parts, 5‑12 parts of titanium diboride fiber, 5‑8 parts of silicon carbide, 3‑5 parts of sodium bicarbonate, 5‑7 parts of antimony trioxide and 3‑5 parts of red mud. The present invention also provides a preparation method of a wear-resistant ceramic material, the method comprising the following steps: (1) weighing 10-15 parts of magnesium carbonate, 10-12 parts of kaolin, 5-12 parts of titanium diboride fiber, carbonizing 5-8 parts of silicon, 3-5 parts of sodium bicarbonate, 5-7 parts of antimony trioxide and 3-5 parts of red mud are added to a high-pressure homogenizer and mixed uniformly; (2) the product of step 1 is placed in an inert Add 65-70 parts of fully ball-milled nano-aluminum oxide under the atmosphere, heat up to 700-710°C, and react for 1-2 hours; (3) Compress the product of step 2, and heat it at a heating rate of 5°C/min to Firing at 1300-1350°C, holding the heat for 2-4 hours, and cooling, the wear-resistant ceramic material is obtained.

Description

technical field [0001] The invention belongs to the field of ceramic materials, in particular to a wear-resistant ceramic material and a preparation method thereof. Background technique [0002] Wear-resistant ceramics are special corundum ceramics made of Al 2 O 3 as the main raw material, added with various components, and fired at high temperature, and then combined with special rubber and high-strength organic / inorganic binders. [0003] Ceramic materials manufactured by utilizing the special functions of ceramics on sound, light, electricity, magnetism, heat and other physical properties are called functional ceramics. There are many types of functional ceramics with different uses. For example, according to the difference in electrical properties of ceramics, electronic materials such as conductive ceramics, semiconductor ceramics, dielectric ceramics, and insulating ceramics can be made. The optical properties of ceramics can be used to manufacture solid-state laser...
