Description of Sintered Corundum Mullite Brick

 

Sintered Corundum Mullite Brick is a type of refractory brick that is produced through a sintering process. It is made from a combination of high-purity corundum and mullite grains, which are carefully selected for their excellent thermal and mechanical properties.
 
The manufacturing process of sintered corundum mullite brick involves carefully proportioning the corundum and mullite raw materials, followed by high-temperature sintering at around 1600-1800°C. This process promotes the formation of strong chemical bonds between the raw materials, resulting in a dense and highly durable brick structure.
 
Corundum is a crystalline form of aluminum oxide (Al2O3) known for its exceptional hardness, high melting point, and chemical stability. Mullite, on the other hand, is a compound of aluminum oxide and silicon dioxide (Al2O3·SiO2), which exhibits excellent thermal shock resistance and high refractoriness.
 
Features of Sintered Corundum Mullite Brick
 
1.High temperature resistance
2.Excellent thermal shock resistance
3.Superior mechanical strength
4.Good chemical resistance
5.Low porosity
 
Application of Sintered Corundum Mullite Brick
Due to its excellent thermal and mechanical properties, sintered corundum mullite brick finds applications in a wide range of industries, including steel, non-ferrous metals, ceramics, petrochemicals, and glass manufacturing, where high-temperature processes and harsh operating conditions are present.
