Fused Mullite Brick

It is made of high bauxite, industrial alumina and refractory clay, with charcoal or coke fine particles as reducing agent, and is made by reduction fusion after molding. Its Al2O3 content is about 72-74%, the apparent porosity is about 17%, the volume density is 2.58g/cm3, the compressive strength at room temperature is about 39.2Mpa, and the softening temperature under load of 0.2Mpa is 1620-1660℃. Compared with sintered mullite bricks, it has better thermal shock resistance, low thermal expansion coefficient, and strong resistance to glass liquid corrosion.
