The Al2O3 content of the Fire clay Brick is from 30-48%.During the manufacturing,first mix the clay chamotte with refractory clay powder,then prepared with clay aggregate into dry mud,high pressure molding,sintering at about 1400C.Under high temperature,the fire clay bricks show weakly acidic,and the ability of resistance to alkaline slag erosion is poor,but with the increase of the content of Al203,the thermal stability of fire clay bricks is better than silica brick, magnesia brick and so on.
