Product Description of High Temperature SK-30 SK32 SK34 SK35
Fireclay Refractory Brick Hot Sale Fireclay Brick Tile
Fireclay bricks are a type of refractory product commonly used in
high-temperature applications, such as in furnaces, kilns, and
other industrial processes. They are composed primarily of clay
clinker (which is a fired and crushed form of clay) as the
aggregate, and refractory soft clay as the binder. The presence of
aluminum oxide (Al2O3) in the range of 35% to 45% gives fireclay
bricks their refractory properties, enabling them to withstand high
temperatures without deforming or degrading.
These bricks are known for their ability to resist heat, abrasion,
and chemical corrosion, making them suitable for environments where
extreme conditions are present. They are widely used in industries
like metallurgy, glassmaking, ceramics, and more.
