Specifications
Refractory brick is a kind of insulation material adoption organic matter as ignition loss substance
in order to increase the porosity, small volume density , good insulation effect, high mechanical
intensity , small thermal conductivity and low heat storage. They are widely used in Fire – Clay
Insulating Refractory Brick, High-Alumina Insulating Refractory Brick , Diatomaceous Insulating
Brick, High Grade Insulation Brick :XJM Series Light-Weight Insulation Brick , B Series Thermal
Insulation Brick, Calcium Silicate Insulating and Refractory Products, Clay Insulation Brick, Foam
Diatomite Insulation Brick, and Light –Weight Insulation Brick.
Lower heat storage than denser refractories

- 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?
- Heavy material has good compactness, high compressive strength, resistance to various corrosive gases, good thermal shock resistance, good thermal conductivity and wear resistance.
- Q: What is the difference between mullite ceramics and alumina ceramics? Can you tell me something to do with floor tiles?
- The floor tiles are not made exclusively of alumina. Pure alumina ceramics are expensive.
- Q: What is the price of refractory bricks?
- The refractory insulating brick generally refers to light brick, normal furnace lining are using this brick kiln will not increase the weight, and good heat insulation effect and ordinary insulating brick production are made of clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating firebrick, diatomite insulating refractory brick, the use of light heat insulation brick can increase the use of space, and good insulation effect
- Q: Mullite bricks in alumina alumina is what?
- Mullite (3Al2O3 - 2SiO2) high alumina refractory materials as the main crystal phase. The general alumina content in 65% ~ 75%. In addition to mineral composition of mullite, alumina containing low also contain a small amount of glass phase and cristobalite; alumina containing high also contain a small amount of corundum. Highrefractoriness, up to over 1790 DEG C 1600. Load softening start temperature to 1700 DEG C. Compressive strength at room temperature is 70 ~ 260MPa.. The thermal shock resistance of 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 alum clay as binder, forming and sintering made of fused mullite bricks with high alumina and bauxite, 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 than sintered mullite, thermal resistance Shock resistance than sintered products. The uniformity of content in alumina mainly depends on their high temperature properties and mullite phase and glass distribution. Mainly used in blast furnace, furnace top and bottom furnace, glass furnace regenerator, sintering kiln, petroleum cracking system dead lining.
- 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
- Tiles are called floor tiles, floor tiles, polished tiles and glazed tiles are glazed tiles, bricks are samples of all kinds of tiles, ceramic tiles will be placed in the tile shop, tiles are also divided into outer wall tiles and inner wall tiles, modern brick and antique brick
- Q: What are the varieties of polycrystalline mullite?
- PMF (polycrystalline mullite fiber) is an international super light resistant high temperature heat insulation material of the latest, it consists of mullite micro crystal which integrates crystal and fiber materials properties in one, has an excellent thermal stability, temperature 1500, melting point 1840, the thermal conductivity of refractory brick is a traditional 1/6, bulk only the 1/25 is the ideal material for high temperature furnace energy saving.
- 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.
