Low Apparent Porosity Mullite Insulating Fire Bricks

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?: Lightweight materials have uniform internal structure, high compressive strength, corrosion resistance, heat shock resistance, oxidation resistance, high temperature and low thermal conductivity.

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: 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?: Performance comparisonWe used chemical method to produce a microcrystalline structure, excellent thermal stability, temperature exceeds the 300~400. C.The small fiber diameter uniform, slag ball trace, bulk density for 1/2~1/3 products.The large amount of fiber products, high porosity, low coefficient of heat conductivity.It has large surface area, is the ideal material for high temperature catalytic carrier.

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.
