$High Temperature Refractory Corundum Mullite Brick$

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: (refractory castable, silicon carbide brick, mullite bricks etc.) do testing should be commissioned by the project? What are the specific qualification standards? Thank you: Different refractory materials have different requirements, specific industry or national standards, such as LZ can check the mullite bricks GB / standard, there should be a harvest, do testing project is in accordance with the requirements of the LZ need to determine the use requirements

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: 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: 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?: In the presence of excess EDTA in the acidic medium, the aluminum is complexed with EDTA, and the remaining EDTA is complexed with lead salt, and then the EDTA complexed with aluminum is replaced by sodium fluoride, and the lead salt is substituted...

Q: The introduction of mullite brick: High alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase.

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: What are the varieties of polycrystalline mullite?: PMF (polycrystalline mullite fiber) is an international super light resistant high temperature heat insulation material of the latest, it consists of mullite micro crystal which integrates crystal and fiber materials properties in one, has an excellent thermal stability, temperature 1500, melting point 1840, the thermal conductivity of refractory brick is a traditional 1/6, bulk only the 1/25 is the ideal material for high temperature furnace energy saving.

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.
