Q:What is the high-grade magnesia spinel brick?
Then there was the second generation of magnesia spinel brick, and its features are changed
Q:The difference between aluminium refractory and magnesia refractory?
Aluminum refractory belongs to neutral refractory material, usually refers to silicon aluminum refractory materials, such as: high alumina brick, clay brick, high alumina castable and other products, the production of raw materials is mainly bauxite.
Q:Spinel compound brick composite layer pollution layer does not affect the use of theoretical basis for it
The study of mg Al spinel synthesized with MgO raw materials and Al2O3 raw materials (calcined alumina or alumina) has begun as early as 1930s. Magnesia alumina spinel was synthesized from industrial alumina and activated alumina in 1939 and used for making bricks. In 40s, people found that the addition of alumina powder in magnesia could improve its thermal stability, this is actually a spinel bonded brick. When the magnesia brick is mainly used in cement kiln, but in addition to the production of white cement kiln, it was replaced by magnesia chrome refractories.
Q:What is the significance of the synthesis of mg Al spinel? What are the main approaches?
Because the thermal expansion coefficient of magnesia alumina spinel is small, the thermal shock resistance of refractory products with its bonding phase is relatively improved.
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 is the primary crystal phase? What is the secondary phase?
The properties, quantities, distribution and bonding state of the main crystalline phases of refractory determine the properties of the products directly. A lot of refractory products, such as mullite brick, corundum brick, magnesia brick, magnesia spinel brick, silicon carbide refractory products, etc., are the main crystalline phase named. What is called a crystalline phase? The second phase and second phase or second phase, refers to the refractory material and the main crystal under high temperature and liquid phase coexist, 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.
Q:What is the structure of magnesium aluminate spinel?
The crystal is composed of eight faces, eight bodies and twelve faces of diamond
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 are the characteristics of Mg rich spinel and aluminium rich spinel?
Occurs in the contact metamorphic zone of acid intrusive rocks and dolomite and dolomitic limestone, and is associated with forsterite, diopside and so on. It is also found in peridotite, Kimberley rock, magnesian porphyry and some crystalline schist.
Q:Spinel refractory brick air-cooled razheng times
The components of magnesia alumina spinel refractories can be magnesia alumina spinel, excessive alumina, or magnesium aluminate spinel with excessive amount of Magnesium Oxide.
