Properties:

1.High hardness (15 to 19 GPa)

2.Moderate thermal conductivity (20 to 30 W/mK)

3.Alumina ceramic has excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential.

4.Alumina (Al2O3) is a hard, chemically resistant material and has the ability to withstand very high temperatures in aggressive environments.
