Polishing and grinding: As the main component of polishing liquid, it is used for grinding and polishing the 

surface of metal materials to achieve perfect polishing effect.

Wear-resistant industry: Due to its high hardness, it is often used to make scratch-resistant and wear-resistant 

coatings, sprayed on the surface of metal, ceramics, plastics and cemented carbide to improve its hardness, 

corrosion resistance and wear resistance, and has anti-fouling, dustproof, waterproof and other functions. It can 

be used for surface protection of machinery, knives, chemical pipelines, etc.

Paint coatings: Applied in the printing ink industry, it can effectively improve the gloss, waterproofness, oil 

resistance and wear resistance of ink.

Refractory and flame retardant: Due to its high temperature resistance, it is often used to manufacture various 

refractory bricks, refractory crucibles, refractory tubes, high temperature resistant experimental instruments, etc., 

and is a common refractory and flame retardant filling material.

Ceramic industry: Alumina ceramic materials have the characteristics of high mechanical strength, high hardness, 

good thermal conductivity, high high temperature insulation resistance, chemical corrosion resistance, etc., and 

are widely used in electronics, electrical appliances, machinery, chemicals, automobiles, aerospace and other 

industries.
