Q:Spinel compound brick composite layer pollution layer does not affect the use of theoretical basis for it
The study of mg Al spinel synthesized with MgO raw materials and Al2O3 raw materials (calcined alumina or alumina) has begun as early as 1930s. Magnesia alumina spinel was synthesized from industrial alumina and activated alumina in 1939 and used for making bricks. In 40s, people found that the addition of alumina powder in magnesia could improve its thermal stability, this is actually a spinel bonded brick. When the magnesia brick is mainly used in cement kiln, but in addition to the production of white cement kiln, it was replaced by magnesia chrome refractories.
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'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:The difference between aluminium refractory and magnesia refractory?
Aluminum refractory belongs to neutral refractory material, usually refers to silicon aluminum refractory materials, such as: high alumina brick, clay brick, high alumina castable and other products, the production of raw materials is mainly bauxite.
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: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
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?
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?
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;
