Introduction of mullite

Mullite (MoNaiShi) is a series of aluminium silicate mineral known collectively, is aluminum silicate at high temperatures generated minerals, artificial heating will form mullite aluminum silicate. Natural mullite crystals as elongated needle and radiation clumps. Mullite ore is used to produce high temperature refractory materials.

Mullite is a kind of high-quality high aluminum refractory material, it has the expansion uniformity, excellent thermal shock resistance, high load softening point, high temperature creep value is small, high hardness, good resistance to chemical corrosion, there are mainly high purity fused mullite, fused mullite sintered mullite, all natural bauxite concentrate and light mullite.

Mullite features

The crystallization of fused mullite is bigger than sintered mullite, good thermal shock resistance than sintered products, they mainly depends on the content of alumina and high temperature performance of mullite facies distribution uniformity of the glass; Fused mullite is a kind of synthetic fused refractory products, crystal as the needle, it has good thermal shock resistance, flexural strength, high refractoriness under load, high hardness, high temperature creep decrescent, etc. System of fused mullite, should keep the atmosphere in the furnace reduction state. Fused mullite colour and lustre is white, low carbon residue, low porosity, low content of impurities, flexural strength, high refractoriness under load, high hardness, high temperature creep, acicular crystals have well developed, mullite, with its excellent thermal shock resistance and abrasion resistance, are widely used in glass kiln body lining bricks, mullite bricks, large blast furnace hot blast stove brick and low creep blast furnace sillimanite brick, ceramic kiln furniture, sagger, shed board, oil chemical industry, etc.

Sintered mullite is made of high quality natural bauxite as raw material, after the selection process and multi-stage homogenization, through more than 1750 high temperature rotary kiln sintering. Fused mullite using high purity quartz sand, alumina industry, on the large electric arc furnace smelting. Sintered mullite has high content, volume density, good thermal shock stability, high temperature creep value small and good resistance to chemical corrosion resistance and other characteristics, stable quality, at the same time, sintered mullite is the production of stereotypes and blank indeterminateness refractories, high-grade sanitary wares, precision casting products such as the ideal raw materials.

Mullite purposes

Suitable for refractories, ceramics, metallurgy, casting, electronics and other industries, has a high temperature resistant, high intensity and small coefficient of thermal conductivity, remarkable energy saving effect is suitable for oil cracking partition kiln, metallurgical hot stove, ceramic kiln, tunnel kiln, electric porcelain crucible kiln drawer kiln, glass and various electric furnace lining, can direct contact with the flame. Mullite work also can be applied to all kinds of flame furnace lining, direct contact with the flame (not contact melt), other high temperature heat preservation and heat insulation equipment, such as:

1, the preparation of various lightweight refractory castable, spray coating, etc.

2, heating furnace, soaking furnace, heat treatment furnace, annealing furnace, ceramic, refractory products sintering furnace, the furnace wall.

3, steam boiler, oil industrial tube furnace, ethane cracking furnace lining.

4, all kinds of industrial furnace door, observation hole lining.
