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?
The synthesis of magnesia alumina spinel mainly uses MgO and Al2O3 raw materials, and is obtained by electro melting, sintering or sintering
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
Q:What is the primary crystal phase? What is the secondary phase?
What are the major crystal phases and phases of refractories? What is called the main crystal phase? The main crystal phase refers to a crystalline phase which constitutes the main structure of the material and has a high melting point and plays a dominant role in the properties of the material.
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?
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?
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.
We are an integrated and synthesis enterprise involved in R & D refractories, structural design of kiln & furnace, production, consstruction, installation, maintenance of refractories. The company has one magnesite and dolomite mine, fused magnesia plant, sintering magnesia plant, three refractories production plant.
