Physical properties of corundum bricks
1. High hardness.
Corundum bricks have very high hardness, and their Mohs hardness can reach level 9, second only to diamond, so they are often used in high-temperature environments that need to withstand high strength and high wear.
2. Wear resistance.
Corundum bricks have very good wear resistance and can withstand long-term erosion and erosion at high speed, high temperature, and high pressure in high-temperature kiln environments.
3. High temperature point. The melting point of
corundum brick is about 2040℃, which can maintain stable performance for a long time in high temperature environment.
4. Corrosion resistance:
Corundum bricks have good corrosion resistance against chemicals such as acids and alkalis, and can maintain stable performance in harsh chemical environments.
