99% Alumina ceramics

Alumina 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 about 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.
6. Thermal Stability: Excellent thermal stability and a low thermal expansion coefficient, allowing them to withstand rapid temperature changes.

Application Industries

1. Electronics and Electrical Industry: Used in the manufacture of insulators, substrates, electronic components, and circuit boards.
2. Mechanical Manufacturing: Used to produce wear-resistant parts, cutting tools, and mechanical seals.
3. Aerospace: Utilized in high-temperature structural materials and turbine engine components.
4. Chemical Industry: Employed in chemical reactor linings, pump components, and valves.
5. Medical Equipment: Used in the manufacture of bioceramics, such as artificial joints and dental implants.
