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

High alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase.

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: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?

Heavy material has good compactness, high compressive strength, resistance to various corrosive gases, good thermal shock resistance, good thermal conductivity and wear resistance.

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 alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase. 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 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?

Mullite refractory bricks can be used in construction, but their price is too high. We choose high alumina brick to meet the demand.
