- 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?
- The properties, quantities, distribution and bonding state of the main crystalline phases of refractory determine the properties of the products directly. A lot of refractory products, such as mullite brick, corundum brick, magnesia brick, magnesia spinel brick, silicon carbide refractory products, etc., are the main crystalline phase named. What is called a crystalline phase? The second phase and second phase or second phase, refers to the refractory material and the main crystal under high temperature and liquid phase coexist, the number and influence on high temperature properties of materials is the main crystal phase is small second phases. As to the main crystalline phase of periclase magnesia chrome brick, magnesia brick, magnesia brick and magnesia calcium brick respectively containing Cr spinel, spinel, forsterite and calcium silicate two are secondary phase.
- Q: Spinel refractory brick air-cooled razheng times
- Magnesium Oxide reacts with alumina at over 1700 degrees to produce spinel.
- 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?
- Then there was the second generation of magnesia spinel brick, and its features are changed
- Q: What is the structure of magnesium aluminate spinel?
- Mg Al spinel is a six square dense stack of equiaxed crystals
- Q: The difference between aluminium refractory and magnesia refractory
- Magnesia refractory belongs to alkaline refractory materials refers to refractory products such as magnesia magnesia brick magnesium iron spinel magnesium aluminum spinel magnesia ramming materials and other products of raw materials is the main crystal phase is periclase magnesia products
- 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.
