95% Alumina Ceramics

The higher the purity of alumina ceramics, the greater their mechanical strength, corrosion resistance, electrical insulation, and thermal stability.

It is one of the most widely used and well-known precision ceramic materials. It exhibits excellent mechanical strength, electrical insulation properties, low dielectric loss, thermal conductivity, and high resistance to heat, wear, and corrosion. The advantages of alumina ceramics and their application industries are outlined below:

Advantages

1. High Temperature Resistance: Alumina ceramics exhibit exceptional heat resistance, with maximum operating temperatures reaching up to 1700°C.
2. High Hardness: With a Mohs hardness of 9, they are second only to diamond, offering outstanding wear resistance.
3. High Strength: These ceramics possess superior mechanical strength and compressive strength, maintaining stability even at high temperatures.
4. Chemical Corrosion Resistance: Highly resistant to corrosion by most acids, bases, and salt solutions.
5. Electrical Insulation: They offer excellent electrical insulation properties, making them ideal for electrical insulating materials.
