Description

{loadposition mypos}

A firebrick is a block of refractory ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces.

A refractory brick is designed mainly to withstand high heat, but should also usually have a low thermal conductivity to save energy. Usually dense firebricks are used in applications with extreme mechanical, chemical, or thermal stresses, Dense fire bricks have a high thermal mass which is sometimes a useful property in that they will retain heat. Fire bricks are made by firing clay based composition until it is partly vitrified,Low alumina Fire bricks usually contain 30-40% alumina and the primary raw material is usually chamotte with other materials. The maximum service temperature of fire bricks increases with increasing alumina content and bricks can be obtained with alumina content of 80% and above.
