Q:What is the structure of magnesium aluminate spinel?
Mg Al spinel is a six square dense stack of equiaxed crystals
Q:What is the significance of the synthesis of mg Al spinel? What are the main approaches?
The synthesis of magnesia alumina spinel mainly uses MgO and Al2O3 raw materials, and is obtained by electro melting, sintering or sintering
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:What's the difference between iron spinel and magnesium aluminum spinel?
Such as aluminum spinel, iron spinel, zinc spinel, manganese spinel, chromium spinel, etc.. Due to the inclusion of different elements, different spinel can have different colors, such as magnesium spinel in red, blue, green, brown or colorless between; zinc spinel is dark green; iron spinel black, and so on.
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: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: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:Spinel refractory brick air-cooled razheng times
The ingredients are magnesium, aluminum, oxygen.
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?
Used to make ladle casting material, greatly improve the corrosion resistance of steel lining. It is widely used in steel making refractory. The preparation of high-quality pre synthesized spinel provides a new raw material for the production of unshaped and unshaped high purity refractories
