Q:What is the high-grade magnesia spinel brick?
Using magnesia as main raw materials, matrix co milling with magnesia and bauxite as alkaline products, high temperature burning, called magnesia brick, also called the first generation of periclase spinel brick.
Q:The difference between aluminium refractory and magnesia refractory?
The difference between the two is one is neutral, one is alkaline, the original product is different naturally.
Q:Spinel compound brick composite layer pollution layer does not affect the use of theoretical basis for it
One is the development of the manufacturing process of the magnesia magnesia purity can be improved, with low content of magnesia silicate phase has good resistance to spalling, does not require the addition of alumina can also produce good thermal shock stability is of high quality magnesia brick; two foreign chromite resources is abundant, magnesia chrome refractories production has thermal stability good and anti erosion ability.
Q:Is magnesium spinel harmful to the body? Such as title magnesium spinel, harmful to the body?
Hospital tests revealed that Alzheimer's patients had more than 5~30 times more aluminum in brain tissue than normal subjects. When the aluminum content in the human body exceeds 5~10 times that of normal people, it can inhibit the absorption of phosphorus by the digestive tract, reduce the level of serum inorganic phosphorus, cause osteomalacia and joint pain. Aluminum chloride and aluminum hydroxide, aluminum alkyl and salt and other drugs, the short term can produce toxic side effects.
Q:What are the uses of magnesia spinel brick in the industry?
Instead of magnesia chrome brick sand manufacturing magnesia spinel brick used in cement kiln, not only to avoid the chrome pollution, but also has good resistance to spalling;
Q:What is the primary crystal phase? What is the 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:What's the difference between iron spinel and magnesium aluminum spinel?
Spinel is a mineral of magnesium aluminum oxide, because it contains elements such as magnesium, iron, zinc, manganese and so on
Q:What are the characteristics of Mg rich spinel and aluminium rich spinel?
Magnesium spinel is a subspecies of spinel, which is MgAl2O4, also called spinel. An equiaxed crystal having eight crystalline or irregularly granular crystals.
Q:Characteristics of sintered spinel used in refractory zzjsnc
For the production of castable for ladle lining steel plate greatly improve the anti erosion ability. It is widely used in steelmaking refractories provides new raw material for the production of high quality synthetic stone pre sintered spinel prepared amorphous and amorphous high purity refractory material
Q:Spinel refractory brick air-cooled razheng times
Magnesium Oxide reacts with alumina at over 1700 degrees to produce spinel.
