Fire brickProvides Protection from the high operating temperatures in the furnace and are More resistant to mechanical damage and chemical attack than insulating Brick.  Fire bricks are composed of various combinations of alumina and Silica containing materials.  the chemical composition can vary from Almost 100% alumina and little silica to 100% silica and little Alumina.  Fire bricks are classified into two broad categories; fireclay and high-alumina bricks. 

Fireclay brick are classified based on physical propeties while high-alumina bricks are classified primarily on alumina content.
