Q:What is the price of refractory bricks?

The construction is superior, the light insulating brick has good machinability, and the construction is convenient and simple, and the labor intensity can be reduced, the construction efficiency can be improved, and the construction period can be shortened. The price is determined by the choice of material and volume density, from several hundred to 5000 yuan, mainly with the choice of material

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: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: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

Compressive strength, volume density, flexural strength, thermal shock resistance, high temperature load, creep temperature, refractoriness, etc.. There should be GB

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 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: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:What are the varieties of polycrystalline mullite?

Chemical composition AI2O3:72 ~ 74%AI2O3+SiO2:~99.6%Main crystalline phase mulliteThe fiber diameter is 2-3.8The specific surface area is 35.5M2/g (1000 DEG C)The burning shrinkage rate was ~1.0% (1500 x6hr)Bulk density 60-100kg/M3The temperature is 1500 degrees centigrade

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.
