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 based on Al 2 o 3 As the main raw material, adding various components, special corundum ceramics are baked 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 lase...
