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.
