Introduction to Alumina Ceramics

Alumina ceramics are known for their high hardness, wear resistance, corrosion resistance, good electrical insulation and high temperature stability. According to the different alumina content, it can be divided into different grades, such as 95 porcelain, 99 porcelain, etc., among which 99 porcelain refers to ceramic materials with an alumina content of 99%. As the alumina content increases, its mechanical strength and electrical insulation properties will also increase accordingly.

Characteristics of Alumina Ceramics

High Hardness: Alumina ceramics have extremely high hardness, which makes it very wear-resistant and suitable for manufacturing abrasive tools and parts that require wear resistance.

Wear resistance: Due to its high hardness, alumina ceramics show excellent wear resistance and are suitable for manufacturing parts for long-term use.

Corrosion resistance: Alumina ceramics have good resistance to most acids and alkalis, making them widely used in the chemical industry.

Good electrical insulation: As an excellent electrical insulating material, alumina ceramics are widely used in electronic and electrical products.

High temperature stability: Ability to withstand extremely high temperatures without significant physical or chemical changes, which makes it an ideal choice for applications in high temperature environments.

Biocompatibility: In the medical field, certain grades of alumina ceramics are used to make medical devices such as artificial joints due to their good biocompatibility.
