Mullite brick

Mullite brick

Mullite brick belongs to high alumina refractory brick, which is a kind of high-grade high alumina brick. Generally, alumina content is between 60% – 75%, which is a high alumina refractory with mullite as the main crystal phase.

Mullite brick (also called mullite refractory bricks) is a kind of fine refractory material, with stable expansion, good thermal stability, high RUL capacity, low creep under high temperature, anti-chemical erosion ability, and have a hard texture.
