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: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:Aluminum content 38, silicon content 55 What refractory bricks?
When the bricks are below Al2O3 71.8%, the base of the composition is mullite and SiO2, such as grade LZ-48 bricks. Because it contains a large number of SiO2 formed in the liquid phase under high temperature is 20% ~ 30%; brick in Al2O3 more than 71.8%, the excess Al2O3 formed corundum crystal under high temperature, while generating 2 high temperature phase, eutectic temperature rise by the low content of Al2O3 brick 1595 C to 1840 C, such as grade LZ-75 brick. In fact, it is impossible to produce a complete phase equilibrium in the process of production, but the glass phase is very small, and there is no more than 10% in the partial gap of the Yu Jing phase
Q:What are the properties of corundum mullite
Heavy material has good compactness, high compressive strength, resistance to various corrosive gases, good thermal shock resistance, good thermal conductivity and wear resistance.
Q:Mullite bricks on 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: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.
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: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: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 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.
