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: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?

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

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'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: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 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 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 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:Spinel refractory brick air-cooled razheng times

The ingredients are magnesium, aluminum, oxygen.
