$High Temperature Refractory Corundum Mullite Brick$

Q: Aluminum content 38, silicon content 55 What refractory bricks?: The mineral composition of the high alumina brick is determined by the bauxite used. The mineral composition of the clinker is usually mullite, corundum and glass. The theoretical composition of mullite is Al2O371.8%, SiO2 28.2%, and its melting decomposition temperature is 1840 DEG C. With acicular crystal, network cross structure, high temperature state showed better strength. Corundum in the form of alpha -Al2O3, melting point of 2050 degrees, hardness of Mohs 9, showing a granular and columnar crystal, has good chemical stability, acid, alkaline slag have a certain resistance. Based on the composition of mullite minerals, the phase composition of high alumina brick can be judged according to the content of Al2O3.

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.
