Fire clay bricks were mainly made from chamotte, flint clay and combining clay powder, being high pressure pressed and sintered in high temperature.
Low porosity bricks are made from low mullite stones, the main mineral composition of the low mullite stones are pressed and sintered mullite phases. The bricks have very good physical and chemical properties in high temperature conditions.
Alumina firebricks Features and advantages:
3.Good corrosion resistance.
4.Good spalling resistance and wear resistance.
5.Good thermal shock resistance.
6.High mechanical strength.
7.High-temperature creep rate is low.
8.Good volume stability at high temperature.
Alumina firebricks are widely used in all parts of furnace lining for middle and small capacity furnace such as glass furnace, blast furnace, hot-air furnace, cement furnace,chemical furnace and other heating engineering equipment.
