Mullite

Specifications

Introduction of mullite

Mullite is a kind of high quality refractory materials, 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 (or MoNaiShi) is a series of aluminium silicate mineral collectively, this kind of mineral is scarce. Mullite is aluminum silicate at high temperatures generated minerals, artificial heating will form mullite aluminum silicate. Natural mullite crystals as elongated needle and radiation clumps. In recent years is widely used in high temperature and engineering materials, electronic packaging materials, optical materials, insulation materials, high temperature refractory, mullite electronic materials and other fields.

Classification of mullite

Sintered mullite: using natural high quality bauxite, through multi-stage homogenization, through more than 1750 ℃ high temperature sintering. Has a large volume density, stable quality, good thermal shock resistance, high temperature creep value performance characteristics such as small and good resistance to chemical corrosion. Mullite is the production of stereotypes and body not stereotypes refractories, high-grade sanitary wares, such as precision casting model ideal raw material of refractory material products.

Fused mullite: selects high quality pure natural mullite ishihara ore, through advanced industrial furnace high temperature burning fuse. Expansion uniformity, excellent thermal shock resistance, high load softening point, high temperature creep value is small, high hardness, good resistance to chemical corrosion, etc. Mullite is metallurgy, ceramics, building materials, chemical industry, electric power and casting of ideal material.

Mullite purposes

Jin Lin corundum refractories co., LTD. Production of mullite produced high temperature mullite stone insulating brick with high temperature resistance, 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 are suitable for all kinds of flame furnace lining work, 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 industry tube furnace, ethane cracking furnace lining;

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