Abstract

The invention discloses a wearable ceramic material belonging to the field of wearable materials. The wearable ceramic material comprises the following raw materials in parts by weight: 85-90 parts ofnano aluminum oxide, 1-3 parts of quartz sand, 5-7 parts of titanium dioxide, 3-5 parts of zirconium dioxide, 1-3 parts of chromic oxide, 10-13 parts of silicon nitride, 0.5-2 parts of thorium dioxide and 3-7 parts of a binder. The wearproof ceramic material has the advantages of enhancement of abrasive resistance and impact resistance, firmer adhesion, improvement of whole performance of materials and high usage degree.

Description

technical field [0001] The invention relates to the field of wear-resistant materials, in particular to a wear-resistant ceramic material. Background technique [0002] Ceramic material is an inorganic non-metallic material made of natural or synthetic compounds after forming and high-temperature sintering. It has the advantages of high melting point and high hardness, and is widely used in more and more industries. Wear-resistant ceramics are special corundum ceramics made of Al2O3 as the main raw material, rare metal oxides as flux, and fired at a high temperature of 1,700 degrees, and then combined with special rubber and high-strength organic or inorganic binders. The product. There is also a higher and higher requirement for the wear resistance of ceramic materials. At the same time, wear-resistant ceramic materials are expensive and not suitable for large-scale industrial production. Contents of the invention [0003] The purpose of the present invention is to prov...
