Corundum brick is a type of refractory brick that is made from high-purity corundum and fired at high temperatures. It is widely used in high-temperature industrial applications where high thermal stability, excellent mechanical strength, and resistance to corrosive environments are required. Some of the key properties of corundum brick include:
1.High temperature resistance: Corundum brick has a high melting point (about 2050°C) and can withstand very high temperatures without losing its strength or structure.
2.Excellent mechanical strength: Corundum brick has high compressive strength and resistance to wear and abrasion, making it suitable for use in harsh and demanding environments.
3.Resistance to chemical attack: Corundum brick is highly resistant to chemical attack by acids and alkaline substances, making it ideal for use in chemically aggressive environments.
4.Low thermal conductivity: Corundum brick has low thermal conductivity, which makes it an effective insulator against heat.
5.Good thermal shock resistance: Corundum brick has good thermal shock resistance, allowing it to resist sudden changes in temperature without cracking or breaking.
6.High purity: Corundum brick is made from high-purity raw materials, which ensures minimal impurities and provides excellent resistance to corrosion and erosion.
7.Low porosity: Corundum brick has low porosity, which enhances its stability and resistance to chemical attack.
In summary, corundum brick is a high-performance refractory material with excellent thermal stability, mechanical strength, and resistance to chemical attack. Its unique combination of properties makes it ideal for use in a broad range of high-temperature industrial applications.
