Fused mullite

Fused mullite, using high purity quartzite and industrial alumina powder as main starting materials, smelting in tilting electric arc furnace, is a new kind of high purity synthesized refractory raw materials. The fused mullite, gray, low residual carbon, is characterized by good acicular crystal structure, high modulus of rupture, symmetrical expansion, and excellent thermal shock resistance, high refractoriness under load, small high temperature creep value, high hardness and good chemical corrosion resistance.
Fused mullite, mainly used for low creep brick for hot blast stove, sillimanite brick, torpedo ladle brick, bricks for high temperature industrial furnaces, lining brick of glass tank, bricks for large-scale iron-making hot blast stove, sagger, deck and other thermal shock resistance ceramics kiln furniture, is an ideal refractories, Fused mullite is also a high quality material improving the toughness of mullite refined ceramic and monolithic refractories.
