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
low levels of iron and other impurities
Lightweight and energy-efficient

- Q: Aluminum content 38, silicon content 55 What refractory bricks?
- When the bricks are below Al2O3 71.8%, the base of the composition is mullite and SiO2, such as grade LZ-48 bricks. Because it contains a large number of SiO2 formed in the liquid phase under high temperature is 20% ~ 30%; brick in Al2O3 more than 71.8%, the excess Al2O3 formed corundum crystal under high temperature, while generating 2 high temperature phase, eutectic temperature rise by the low content of Al2O3 brick 1595 C to 1840 C, such as grade LZ-75 brick. In fact, it is impossible to produce a complete phase equilibrium in the process of production, but the glass phase is very small, and there is no more than 10% in the partial gap of the Yu Jing phase
- Q: (refractory castable, silicon carbide brick, mullite bricks etc.) do testing should be commissioned by the project? What are the specific qualification standards? Thank you
- If there is no mark, ask the laboratory of the production factory to analyze any chemical or physical items. Or, check the national standard, the national standard has the basic requirements of the physical indicators
- 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.
- 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
- Mainly used for hot blast stove of blast furnace and furnace bottom and furnace, glass furnace regenerator, sintering kiln, petroleum cracking dead lining system.
- 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: 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.
