99.5% alumina ceramic, alumina 99.5% above, high density, wear-resistant acid corrosion, high temperature (1400-1500 degrees Celsius), chemical stability, high insulation, strong adsorption, it is a very good electrical insulation wear-resistant materials.
Uses: Widely used in electronic appliances, mechanical seals, petrochemicals, auto parts, wear parts, etc.
Features:
1. High resistivity
2. Moderate strength
3. Excellent eletrical properties
4. Poor heat conductivity(Thermal insulator)
5. Good resistance to thermal shock
6. Low coefficient of thermal expansion
7. Good mechanical stability
We can supply the products according to customer's drawings, samples and performance requirement.
Steatite ceramic is commonly used in application thermostat where a high temperature electrical insulator is needed that will hold its shape and size and will not wear out, it works very well in cold switching applications, and used to support heating elements in electric heaters ,toasters,and ovens.
