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 is the significance of the synthesis of mg Al spinel? What are the main approaches?
The spinel has high hardness, chemical stability, high melting point and good properties, high temperature resistance in various melt erosion is very strong, so the orebody in spinel, improve the high-temperature performance of the product. Although the spinel has the above properties, the natural magnesium aluminum spinel is very few and can not meet the needs. Therefore, the synthetic method is usually used in modern times.
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 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: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:What is the high-grade magnesia spinel brick?
Then there was the second generation of magnesia spinel brick, and its features are changed
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?
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 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
