- 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?
- 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: 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?
- 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: 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: What is the structure of magnesium aluminate spinel?
- Mg Al spinel is a six square dense stack of equiaxed crystals
- 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
