10.What is alumina ceramic?

Alumina ceramic, or aluminum oxide (Al2O3), is an industrial ceramic that has high hardness, is long wearing, and can only be formed by diamond grinding. Alumina ceramics are made from a white granular material or a very fine silky dense powder refined from bauxite.

11.What are the benefits of alumina ceramics?

Alumina ceramics is a widely used material because it can be produced in a range of purities—from 85 to 99.9 percent pure—that provide unique benefits. Generally, alumina ceramic components offer quality strength, hardness, corrosion resistance, and thermal stability.
