Fire clay bricks are typically used as linings for kilns, furnaces and boilers they possess mechanical strength and can be subjected to extreme thermal cycling and thermal shock. Fire clay bricks also have a high thermal mass which ensures they retain heat and provide excellent energy efficiency.
Fire clay bricks are made by firing clay based composition until partly vitrified, normally fire clay bricks contain 40-50% alumina depending on the maximum operating temperatures.
