Mullite Brick is a refractory material characterized by excellent performance (especially high temperature creep performance), is made from pure mullite and also alumina powder is added according to different types, finally sintered at high temperature. The features of our mullite bricks are with high mechanical intensity; high refractoriness, contact with flame directly; high porosity, low volume density, low thermal conductivity; low creep rare at high temperature, good thermal shock stability; chemical corrosion resistance and long service life.
