Mullite insulating brick is produced by synthetic mullite sand and polystyrene sphere which has better performance than clay insulating brick and high alumina insulating brick. This product is pure white product, and the content of Fe2O3 and impurity is lower. It has good thermal shock resistance
1.High refractoriness under load 2.Good thermal shock resistance
3.Low permanent linear change on reheating
Mullite bricks can be used in petroleum partition kiln, metallurgical hot stove, ceramic kiln, tunnel kiln and as linings of many stoves.
