Summary

Mullite is a high-quality refractory material, it has a uniform expansion, hot pillow with excellent stability, load softening point is high, the high temperature creep characteristics of small, high hardness, resistance to chemical corrosion and good value, high purity fused mullite, common fused mullite, all natural bauxite concentrate sintering mullite and light burned mullite.

Mullite classification
A sintered mullite
Sintered Mullite with natural high-quality bauxite, through multi-stage homogenization, by more than 1750 DEG C high sintering temperature. Has the characteristics of high bulk density, stable quality, good thermal shock stability, high temperature creep value and good corrosion resistance. Is in the production of various shaped and unshaped refractory materials, high-grade sanitary wares blank body, precision casting model refractory products are the ideal raw material.
Two, lightweight mullite aggregate
Light Mo mullite is not only the natural bauxite as raw material, the reasonable process for use in 1400-1500 DEG C high temperature lightweight aggregate. Mullite features: 1, the use of high temperature, can directly contact the working lining using flame, high temperature energy saving. 2, coefficient of thermal conductivity low, good insulation properties, special light Mo mullite aggregate batching, volume stability, high strength, tight structure better. 3, weight 40--60%, eliminate hidden broken roof hanging brick. 4, quick drying, high porosity smooth exhaust, shorten oven period, significant economic benefits.
Lightweight mullite use: various flame furnace lining, direct contact with the flame (not contact melt), other high temperature equipment insulation; preparation of various lightweight refractory castable, spray coatings; heating furnace, soaking furnace, heat treatment furnace, annealing furnace, ceramic, refractory products firing furnace furnace roof and wall; steam boiler, oil industry pipe type heating furnace, ethane cracking furnace lining; all kinds of industrial furnace door, observation hole lining.
Three, calcined mullite
The natural calcined mullite products using high-quality kaolin as raw materials, processed by high temperature calcination. The product has the characteristics of high density, high hardness, small expansion coefficient, excellent wear resistance and good thermal stability. Mainly used in metallurgy, building materials, chemical industry, refractory materials, military and other industries.
Four, fused mullite
Natural selection of high-quality mullite ore, the advanced industrial furnace and high temperature melting. With uniform expansion, excellent thermal shock resistance, load softening point is high, the high temperature creep characteristics of small, high hardness, resistance to chemical corrosion and good value. Mullite is an ideal material for metallurgy, ceramics, building materials, chemical industry, electric power and casting industry.
