White α corundum brick
White α corundum brick Introduction
αcorundum brick has high structural strength to resist fire and high temperature. It is the best suitable brick for cooling pool and supuerstructure of glass kiln, as well as non-ferrous metal smelting furnace and high-temperature tunnel kiln, etc.
White αcorundum brick Features
1.high density& temperature resistibility
2. low bulk density, high compressive strength,
3. resistance to high temperature(≥1790℃)
4. good thermal shocking resistance
5. excellent corrosion resistant to acids and alkalis
