Light weight mullite  bricks 

Mullite bricks

Mullite brick is a refractory material with an alumina content of 65~75%, a refractory degree of up to 1790°C, and a surface softening temperature of 1600~1700°C. Cold crushing strength is 70~260MPa

High alumina brick

High alumina brick main ingredient is Al2O3, it is a high hardness compound, has excellent corrosion resistance and abrasion resistance, and the working temperature is high at 1850℃.

Alumina bubble bricks are made of alumina bubble balls and alumina powder as the main raw materials, combined with other binders, and fired at a high temperature of 1750 degrees.
