Fire Clay Brick

Fire Clay Bricks is a kind of clay products with 30~40% Al2O3 content. ClayFire Bricks are most widely used in industrial kiln application with various features of cheap, wear resistance, low thermal conductivity, good thermal insulation, easy operation and installation.

Description for Fire Clay Brick for Sale

Mineral composition of clayfire bricks are mainly kaolinite (Al2O3·2SiO2·2H2O) and 6~7% impurities (oxide of Ka, Na, Ca, Ti, Fe). The firing process is mainly dehydration and decomposition of kaolinite continually. SiO2 and Al2O3 in firing process with impurities form eutectic melting point of silicate and surround around the mullite crystal.

Clayfire bricks belong to faintly acid refractory product that can resist acid slag and gas erosion. It has a bad resistance to basic compounds. But its thermal shock property is good.
