Q:Is magnesium spinel harmful to the body? Such as title magnesium spinel, harmful to the body?: Extremely harmful! Studies have shown that brain tissue has affinity for aluminum, and excessive deposition of aluminum in brain tissue can cause memory loss, mental retardation, slow action and aging.

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: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 high-grade magnesia spinel brick?: Then there was the second generation of magnesia spinel brick, and its features are changed

Q:Spinel refractory brick air-cooled razheng times: The ingredients are magnesium, aluminum, oxygen.

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 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: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 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 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.
