- 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: 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: 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 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
- The difference between the two is one is neutral, one is alkaline, the original product is different naturally.
- 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: 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
