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: 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: 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: What's the difference between iron spinel and magnesium aluminum spinel?: Spinel is a mineral of magnesium aluminum oxide, because it contains elements such as magnesium, iron, zinc, manganese and so on

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 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 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?: 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?: The synthesis of magnesia alumina spinel mainly uses MgO and Al2O3 raw materials, and is obtained by electro melting, sintering or sintering
