- Q:What is the difference between corundum and high alumina?
- The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
- 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 main component of corundum?
- Corundum is the main component of Al2O3, often containing trace impurities such as Cr, Ti, Fe, V and so on.
- 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:How do corundum bricks bind?
- Each refractory brick is provided with corresponding refractory mud, and corundum bricks are bonded with corundum mud.
- Q:What are the main constituents of refractory bricks?
- Corundum refractory brick and corundum brick is a kind of refractory brick with AL2O3 content not less than 90% and corundum as its main phase. It can be divided into sintered corundum bricks and fused corundum bricks.
- Q:Ask for help about the phase of refractory material
- Binding phase. The binding phase is the phase outside the main crystal phase or the main crystal phase and the sub crystalline phase. The binding phase can be made up of either a fine crystal or a glass phase or a composite of the two. Such as the combination of magnesia brick, magnesia chrome brick, magnesia brick and other basic refractories in phase is composed of crystal matrix; silica brick, clay brick is made of glass phase in the form. When the matrix is formed at high temperature, the liquid phase is low, and the viscosity of the liquid phase is low and the quantity is large, the production and properties of refractory products are essentially controlled by the substrate.
- Q:What are the advantages of refractories?
- Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.
- Q:What can zirconium sponge do for those industries?
- Uses: aerospace, military, nuclear reactions, atomic energy, and metal superhard materials, the manufacture of bulletproof alloy steel, can also be used in the reactor uranium fuel coating alloy; zirconium at high temperatures easy to launch electronicProduct characteristics: zirconium metal has very strong corrosion resistance, ultra high hardness and strength
- 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.
