The Description of alumina ceramic
Alumina ceramic are found across a huge number of user industries due to cost-effective advantages and high-performance solutions. The combination of key properties makes them a go-to product in many different applications:
1. High mechanical properties
In the field of machinery and equipment, alumina plays a crucial role as it serves as an essential component for numerous structural and engineering ceramic parts.
2. Thermally stable
High purity alumina (Al2O3) can be used in both oxidizing and reducing atmospheres up to 1600°C (2910°F) and in vacuum furnaces up to 1750°C.
3. High chemical resistance
Alumina is chemically inert and not corroded by water or steam. It offers good resistance to corrosive substances such as strong
acids or alkalis, even at elevated temperatures.
Electrical insulation - Alumina is also widely used as an electrically insulating material. It can be used for insulators
operating at high temperatures (e.g. furnace lead-in tubes, fuel-cells)
