Properties of Alumina Ceramics
Alumina ceramic, or aluminum oxide (Al2O3), are valued for their superior performance in various industrial applications. Key properties include:
- Alumina Content: Available in purity levels from 99% to 99.8%, higher alumina content offers enhanced resistance to wear, corrosion, and electrical conductivity.
- Crystal Phases: Variations like mullite and corundum impact mechanical properties, making them suitable for different uses.
- Additives: Additives such as chromium and titanium enhance specific properties, allowing for tailored solutions.
- Electrical Insulation: Alumina is an excellent electrical insulator, with resistance increasing with purity, ideal for high dielectric strength applications.
- Thermal Properties: It has a high melting point and strong mechanical strength, though this strength decreases above 1000°C. It also has excellent thermal conductivity but lower thermal shock resistance.
Applications of Alumina Ceramics
The unique properties of alumina ceramics make them suitable for a wide range of applications:
- Acid-Resistant Components: Used in acid-resistant pump parts and pipe linings due to their chemical stability.
- Textile and Metalworking: Their hardness and wear resistance are ideal for textile wear parts, knives, and abrasive grains.
- Abrasives: Commonly used as abrasive grains in woodworking and metalworking for better performance on various materials.
- Lighting and Detection: Transparent alumina is used in high-pressure sodium lamps and infrared detection windows.
- Electrical Insulators: High-purity alumina serves as an excellent electrical insulator with low dielectric loss, making it ideal for electronics.
