Light Weight Mullite Insulation Brick can be widely used for lining or insulation layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry.Application:

Q: Aluminum content 38, silicon content 55 What refractory bricks?: Semisilica brick: the content of Al2O3 is 15% ~ 30% of aluminium silicate refractory products. Manufacturing products are semi silica quartz containing impurities or native clay kaolin, refractory clay or kaolin beneficiation tailings and the pyrophyllite

Q: What are the properties of corundum mullite?: Lightweight materials have uniform internal structure, high compressive strength, corrosion resistance, heat shock resistance, oxidation resistance, high temperature and low thermal conductivity.

Q: What is the difference between mullite ceramics and alumina ceramics? Can you tell me something to do with floor tiles?: Corrosion resistance: mullite acid is not alkali resistant. Alpha alumina ceramic acid, alkali resistance - for floor tiles, alumina corrosion resistance is too high, unnecessary.Sintering temperature: the sintering temperature of mullite is low. So the cost is low because of this, so alumina ceramic is basically not used for floor tiles - unless it's too rich to burn.Heat shock resistance: the thermal shock resistance of mullite is higher than that of alumina.High temperature creep properties: the high temperature creep of mullite is higher than that of alumina, so mullite can bear higher weight at high temperature, and alumina is less.Resistance: alumina ceramic resistor is higher than mullite, so it is used as high-voltage insulators.

Q: What is the price of refractory bricks?: The construction is superior, the light insulating brick has good machinability, and the construction is convenient and simple, and the labor intensity can be reduced, the construction efficiency can be improved, and the construction period can be shortened. The price is determined by the choice of material and volume density, from several hundred to 5000 yuan, mainly with the choice of material

Q: Mullite bricks in alumina alumina is what?: Quality solutionsMullite brick:With mullite as main crystalline phase of high alumina refractory products. Mullite bricks containing Al2O3 64%~75%, refractoriness >1790? C, normal temperature compressive strength 70~260MPa, softening the starting point for 1600~1700 degrees. The manufacturing method for casting and sintering process.

Q: Jm26 mullite aluminum content in the number, ask God to answer. 23 more. How is this identified with the naked eye?: Under strong alkaline conditions, aluminum is separated from other metal ions by the amphoteric nature of aluminum.

Q: Mullite brick: High refractoriness, up to 1790 degrees celsius. The softening start temperature is 1600~1700 degrees. The compressive strength at normal temperature is 70 ~ 260MPa. Good thermal shock resistance. The sintered mullite and fused mullite brick two. Sintered mullite brick with high bauxite clinker as the main raw material, adding a small amount of clay or raw bauxite as binder, after molding, sintering and made. Fused mullite brick with high bauxite, alumina and refractory clay as raw material, adding charcoal or coke fines as a reducing agent, formed by reduction of electric melting method to manufacture. The crystallization of fused mullite is larger than that of sintered mullite, and the thermal shock resistance is better than that of sintered products. Their high temperature performance mainly depends on the content of alumina and the uniformity of the phase distribution of mullite and glass. [1]

Q: The difference between the high aluminum corundum brick and corundum mullite brick: Wall tiles and floor tiles are collectively referred to as ceramic tile flooring

Q: What are the varieties of polycrystalline mullite?: Chemical composition AI2O3:72 ~ 74%AI2O3+SiO2:~99.6%Main crystalline phase mulliteThe fiber diameter is 2-3.8The specific surface area is 35.5M2/g (1000 DEG C)The burning shrinkage rate was ~1.0% (1500 x6hr)Bulk density 60-100kg/M3The temperature is 1500 degrees centigrade

Q: Refractory bricks (mullite bricks) can be used on the walls of buildings?: Mullite refractory bricks can be used in construction, but their price is too high. We choose high alumina brick to meet the demand.
