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:Spinel compound brick composite layer pollution layer does not affect the use of theoretical basis for it
One is the development of the manufacturing process of the magnesia magnesia purity can be improved, with low content of magnesia silicate phase has good resistance to spalling, does not require the addition of alumina can also produce good thermal shock stability is of high quality magnesia brick; two foreign chromite resources is abundant, magnesia chrome refractories production has thermal stability good and anti erosion ability.
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?
The long-term intake of aluminum will eventually harm the health of the human body. These two elements are not soluble and can cause pneumoconiosis and lung cancer after inhalation.
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 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: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
