Mullite bricks are sintered mullite bricks and fused mullite bricks.
Mullite Insulating Firebrick refractoriness higher, up to 1790 ℃ or more. The softening start temperature of the load is 1600 to 1700 ° C. Room temperature compressive strength of 70 ~ 260MPa. Thermal shock resistance is good.
Mullite bricks are sintered mullite refractory brick and fused mullite bricks. Sintered mullite brick to bauxite clinker as the main raw material, adding a small amount of clay or bauxite as binder, by molding, firing and made. Fused mullite bricks to high bauxite, industrial alumina and refractory clay as raw materials, by adding charcoal or coke fine particles as reducing agent, forming after the use of reduced melting method to manufacture. The fused mullite is more crystalline than the sintered mullite and has a better thermal shock resistance than the sintered product. Their high temperature properties depend mainly on the alumina content and the homogeneity of the mullite phase with the glass distribution. Mainly used for hot stove top, blast furnace and the bottom of the furnace, glass furnace regenerator, ceramic sintering kiln, oil cracking system, such as dead angle lining.

Mullite Insulating Firebrick---Refractory Brick---Refractory Material---Changxing Refractory
Mullite Insulating Firebrick
Introduction：
Light Weight Mullite Insulation Brick can be widely used as lining or insulation layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry.
Advantages：
products containing a large number of closed pores, and a lightweight high temperature, good insulation properties, refiring small contraction, excellent thermal shock resistance, strong resistance to the corrosive gas and slag. Products can greatly improve the thermal efficiency of the kiln to shorten the production cycle, reduce the kiln body weight to achieve energy saving.
Application：
It has excellent thermal shock resistance, strong resistance to the corrosive gas and slag.
