General Information of Mullite Brick-MS74

Our mullite brick is a kind of high alumina refractory brick which takes the mullite (3Al₂O₃ · 2SiO₂) as the basic crystalline phase. Alumina content is generally from 65% to 75%. Featuring high compressive strength, good thermal stability and strong impact resistance. It can be made into any specification defined by users to fit for different demands. It also has the capacity of maintaining excellent mechanical behavior under high temperature,

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: (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?: Mullite is formed by the reaction of alumina with silica. The main difference between him and alumina is that:Hardness: alumina is harder than mullite, but two are tough enough, and are not easy to break.Corrosion resistance: mullite acid is not alkali resistant. Alpha alumina ceramic acid, alkali resistance - for floor tiles, alumina corrosion resistance is too high, unnecessary.

Q: Jm26 mullite aluminum content in the number, ask God to answer. 23 more. How is this identified with the naked eye?: In the presence of excess EDTA in the acidic medium, the aluminum is complexed with EDTA, and the remaining EDTA is complexed with lead salt, and then the EDTA complexed with aluminum is replaced by sodium fluoride, and the lead salt is substituted...

Q: The introduction of mullite brick: General alumina content in 65% ~ 75% between. In addition to mullite, the mineral composition contains lower amounts of glass phase and square quartz, and alumina containing a small amount of corundum.

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: Wall tiles and floor tiles are collectively referred to as ceramic tile flooring

Q: What are the varieties of polycrystalline mullite?: PNF-100 seriesThe PNF-100 series are made of polycrystalline mullite fiber cotton felt to cut, compress, and wrap into blocks without any adhesive.Characteristic: thermal shock resistancelow thermal conductivityLight weightSound absorption propertyLow thermal storage

Q: Refractory bricks (mullite bricks) can be used on the walls of buildings?: In many architectural design, high-rise fire rating is placed in the important position of the topic, especially when the floor height is more than 20 layers, we have more stringent requirements for the choice of fire resistant materials. The building wall, kitchen flue, boiler flue, flammable zone must use a firewall barrier, in many refractory refractory brick is the product of choice for fire resistance of refractory brick masonry is more stable.
