Description
Fireclay (chamotte) brick is a type of refractory material made primarily from refractory clay or chamotte, which is fired at high temperatures. The main component is aluminosilicate. These bricks have good fire resistance, thermal stability, and slag resistance. They are generally categorized into: fireclay bricks, dense fireclay bricks, low-creep fireclay bricks, and thermal shock-resistant fireclay bricks.
