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 castable, silicon carbide brick, mullite bricks etc.) do testing should be commissioned by the project? What are the specific qualification standards? Thank you
Is there a mark on the contract? Mark the items as required by the contract.
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: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: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: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: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.
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:Mullite bricks on 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: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.
