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?: 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: 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 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?: Magnesium spinel is a subspecies of spinel, which is MgAl2O4, also called spinel. An equiaxed crystal having eight crystalline or irregularly granular crystals.

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?: The crystal is composed of eight faces, eight bodies and twelve faces of diamond

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 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
