Q:What is the price of refractory bricks?

The refractory insulating brick generally refers to light brick, normal furnace lining are using this brick kiln will not increase the weight, and good heat insulation effect and ordinary insulating brick production are made of clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating firebrick, diatomite insulating refractory brick, the use of light heat insulation brick can increase the use of space, and good insulation effect

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

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

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 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: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: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.
