FAQs
Q1: What is an Alumina Corundum Brick?
Alumina Corundum Brick is a type of refractory brick made primarily from alumina (Al₂O₃) and corundum (crystalline aluminum oxide). It is designed to withstand high temperatures, thermal shock, and chemical corrosion, making it ideal for use in furnaces, kilns, incinerators, and reactors.
Q2: How do I choose the right Alumina Corundum Brick for my application?
- Maximum operating temperature and thermal cycling conditions.
- Chemical environment (exposure to slags, acids, alkalis, or other corrosive substances).
- Mechanical stress and wear conditions.
- Desired size, shape, density, and porosity.
Q3: Are Alumina Corundum Bricks resistant to thermal shock?
Yes, Alumina Corundum Bricks have excellent thermal shock resistance, allowing them to withstand rapid temperature changes without cracking or degrading.
