- 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?
- 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: 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.
- Q: Is magnesium spinel harmful to the body? Such as title magnesium spinel, harmful to the body?
- Extremely harmful! Studies have shown that brain tissue has affinity for aluminum, and excessive deposition of aluminum in brain tissue can cause memory loss, mental retardation, slow action and aging.
- 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: Spinel compound brick composite layer pollution layer does not affect the use of theoretical basis for it
- The chemical composition of magnesia spinel brick has an important effect on the performance of. The suitable chemical compositions of spinel are 8%~20%, cao0.5%~1.0%, fe2o30.2%~8%, sio2<0.4%, B2O3 and alkali. The impurity content is less than 0.3%, and the rest is mgo. When the Al2O3 content is less than 8%, less content of spinel crystals, intergranular directly binding to periclase and periclase magnesia brick, showing the shortcomings, namely spalling resistance difference. When the content of Al2O3 is more than 20%, the corrosion resistance of brick decreases. When cao<0.5%, fe2o3<0.2%, spinel mineral crystal is less than 5mm or more hours, almost as crystal direct binding between periclase and periclase, which shows the disadvantages of magnesia brick. With the increase of the content of Cao and Fe2O3, the liquid phase formed by the low melting point of cao-al2o3-fe2o3 system is formed, which makes the spinel crystal grow up and the anti flaking property produced by the spinel crystal can be exploited. But when cao>1%, fe2o3>0.8%, cao-al2o3-fe2o3 system low melting point liquid phase increased spinel crystal size is more than 20mm, because cao-al2o3-fe2o3 system low melting material increased the thermal strength decreased. When the content of SiO2 is more than 0.4% and the content of impurities such as B2O3 and base is more than 0.3%, more low melting substance is produced, and the thermal strength of the brick decreases. The content of Al2O3 in the range of 8%~20%, the microstructure can be observed on spinel mineral evenly distributed in the periclase spinel mineral, the crystal size is about 5~20mm, the better comprehensive performance of brick.
- 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 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: Characteristics of sintered spinel used in refractory zzjsnc
- Sintered aluminum magnesium spinel has good anti erosion ability, anti abrasion ability of good heat shock stability and its main use: instead of magnesia chrome sand manufacturing aluminum magnesium spinel brick used in cement rotary kiln to avoid the chrome pollution but also has good resistance to spalling
