magnesia aluminate spinel bricks with high quality

Q: Zirconium corundum 25 content and 40 content, how to distinguish in appearance?: The fused zirconia corundum brick is mainly made of fused zirconia and corundum. ZrO2-Al2O3-SiO2 three element system fused brick, containing Al2O3:40% to 50%, ZrO2:30% to 50%, SiO2:10% to 17%.From the point of view of data analysis, there is no radioactive substance in it, and it will not cause harm to the human body.

Q: What is the price of concrete self insulation bricks?: Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.

Q: What does refractory consist of?: According to the shape of the product is shaped and unshaped refractory materials two categories, according to the chemical properties of acidic, neutral and alkaline refractory materials three categories, commonly used as refractory material of alkaline and neutral, such as magnesia, alkaline burned magnesia brick, magnesia chrome brick, magnesia calcium brick, high alumina brick, corundum neutral brick, clay brick, including: unshaped castable, ramming material, gunning material, coating material, dry vibration material etc..

Q: Which is good, glazed brick and whole cast glazed brick?: The main advantages of all glazed glazed tiles are that they can be very rich and beautiful in texture and pattern, and they are suitable for family decoration, and can choose patterns according to their own family decoration style. Compared to the glazed tile, it has better pollutant discharge performance, and many pollutants are difficult to penetrate into it.

Q: Expansion ratio of lightweight corundum refractory bricks: Light corundum refractory brick, because of its production methods and the introduction of different additives, there are certain differences in the content of Al2O3, just burn add general light corundum refractory brick and foam and gasification method cannot be made, the content of Al2O3 is generally not more than 99%, with alumina hollow ball manufacturing transfer are corundum brick with high content of Al2O3.

Q: Is liquid phosphoric acid two aluminum hydrogen flammable?: Two aluminum liquid hydrogen phosphate using spray paint, cement, refractory castable and binder for foundry industry, mainly used in refractory industry corundum, chromium corundum nozzle coal water slurry gasifier with chromium aluminum zirconium corundum brick production.

Q: Ask for help about the phase of refractory material: Secondary crystalline phase. The second phase and second phase or second phase, and the main crystal phase and is in high temperature liquid phase coexistence in refractory material, the number and influence on high temperature properties of materials is the main crystal phase is small second phases. As to the main crystalline phase of periclase magnesia chrome brick, magnesia brick, magnesia brick and magnesia calcium brick respectively containing Cr spinel, spinel, forsterite and calcium silicate two are secondary phase. There are structure of refractory refractory material in the crystal phase, especially the direct combination of high melting point and so on, the resistance to high temperature also tend to benefit. Compared with the ordinary brick, the second phase of the refractory products, make the products refractoriness under load are improved. Many according to mineral composition of refractory material named, such as mullite corundum brick, corundum mullite brick, is its main crystal phase and the second phase composite named. The former is mainly crystal phase, the latter is sub crystalline phase.

Q: Can the fire clay be reused?: Refractory soil cannot be reused.Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.

Q: What kind of rock is corundum produced?: If Ti4+ and Fe2+ containing a small amount of blue, a sapphire; containing six symmetrically distributed acicular rutile or other inclusions in some crystals, can produce six star awn, known as star ruby or sapphire stars, are precious stones. Corundum is vitreous luster with no cleavage, but cracks occur because of the presence of poly twin crystals that are often formed by the base or face of a face. Specific gravity 3.98. Of relatively low silicate igneous and metamorphic rocks and common in alluvial deposits. The U.S. state of North Carolina and Georgia, Russia's Ural mountains, South Africa as the main origin of the transvaal.

Q: What can zirconium sponge do for those industries?: Zirconium metal, also known as sponge zirconium, silver gray metal, the appearance of steel, shiny; melting point 1852 points, sub points, boiling point 4377 density 6.49. Zirconium is easy to absorb hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxygen; at 1000 DEG C oxygen dissolved in zirconium can make its volume increase significantly. Zirconium is relatively stable in the air; powder zirconium is easy to burn; fine zirconium wires can be ignited by matches; at high temperatures they can be combined directly with dissolved oxygen, nitrogen and hydrogen.
