Chemical composition of Magnetite Chemical composition: FeO31.03, Fe2O368.96. Among them, the isomorphic substitution of Fe3 includes Al3, Ti4, Cr3, V3, etc; Substitutes for Fe2 include Mg2, Mn2, Zn2, Ni2, Co2, Cu2, Ge2, etc. When Ti4 replaces Fe3, it is accompanied by Fe2-Fe3, Mg2-Fe2, and V3-Fe3; Ti can also exist in the form of directional intergrowth of small inclusions of Ilmenite or ilmenite, which is exsolved from Solid solution. At>600 ℃, Magnetite FeFe2O4-Fe2TiO4 complete Solid solution is formed, and the mineral structure formula is Fe3 [Fe21-xFe31-2xTi4x] O4 (0 ≤ x ≤ 0.2); Fe31.2-xFe2x-0.2 [Fe21.2Fe30.8-xTi4x] O4 (0.2 ≤ x ≤ 0.8); Fe32-2xFe22x-1 [Fe22-xTi4x] O4 (0.8 ≤ x ≤ 1); The cations in square brackets are Octahedron coordination. FeFe2O4-FeTiO3 complete Solid solution is formed at>500 ℃; With the decrease of temperature, Solid solution exsolved. When Ti4 replaces Fe3, when TiO2 is 25%, it is called titanium containing Magnetite. When there is more vanadium and titanium, it is called vanadium titanium Mag: 25

Magnet separation range Magnetite is the ore of oxide mineral Magnetite, belonging to equiaxed crystal system. The crystals are Octahedron and Dodecahedron, with stripes on the crystal face, and are mostly granular aggregates. Iron black, or with dark blue indigo color, black stripes, semi metallic luster, opaque, without cleavage, uneven fracture surface, hardness of 5.5-6.5, density of 5.16-5.18g/cm3, is the most magnetic mineral and can be attracted by permanent magnets. The ancient Chinese compass "Sinan" was made using this characteristic. Crisp, odorless, tasteless. It often occurs in magmatic rocks, Metamorphic rock, and coastal sands. Distributed in Shandong, Hebei, Henan, Liaoning, Heilongjiang, Inner Mongolia, Hubei, Yunnan, Guangdong, Sichuan, Shanxi, Jiangsu, AnhuiMagnetite is widely distributed and has many origins. Kiruna, Sweden is a typical magmatic deposit. The Laco iron ore deposit in Chile is directly formed by the slurry related to Volcanism. The iron ore formed by contact metamorphism can: 25

Magnite Mineral name. The chemical composition of Magnetite is Fe3O4, and the crystal belongs to Oxide mineral of equiaxed crystal system. The crystal is usually Octahedron and Rhombic dodecahedron, and the aggregate is granular or massive. The intact single crystal is Octahedron or Rhombic dodecahedron, and when it is Rhombic dodecahedron, the diamond plane often has stripes parallel to the long diagonal direction of the crystal plane. Aggregates are dense block or granular. The color is iron black, with black streaks, metallic or semi metallic luster, opaque, no cleavage, Mohs hardness of 5.5-6, and specific gravity of 4.8-5.3. Because it has strong magnetism, it is called a magnet in ancient Chinese books, indicating its magnetism; In addition, there are names such as iron ore, magnetite, and Xuanshi. The iron content is 72.4%, making it the most important iron ore. If the ore contains very few harmful elements, it can be directly used for open hearth steelmaking. Many Magnetite also contai: 25

DC electromagnet DC electromagnet, the presence or absence of electromagnetic field can be controlled by on/off current, which includes an iron core, armature mechanism, excitation coil (L), and excitation coil (L) wound around the iron core.A direct current electromagnet, which includes an iron core, an armature mechanism, and an excitation coil (L). The excitation coil (L) is wound around the iron core, and is characterized in that the excitation coil (L) is connected in series with a positive temperature coefficient thermistor (RT) and connected to a direct current power supply (DCV). The utility model can save a large amount of electrical energy in use.Electromagnets have many advantages: the presence or absence of electromagnetic field can be controlled by on/off current; The strength of the magnetic field can be controlled by the strength of the current or the number of turns in the coil (or by controlling the size of the iron core); Its magnetic poles can be controlled by changing the direction: 25

Impact magnet The impact magnet is a magnet with an empty core current plate structure, used to change the trajectory of the electron beam for injection and extraction. In order to deflect the beam effectively, the impact magnet is required to generate a high pulsed magnetic field with a certain flat top width within a very short rise and Fall time time. The impact magnet power supply adopts a centralized layout of 4 impact magnet injection systems to improve the stability of the light source operation and improve the performance indicators of the light source. Four ferrite impact magnets are all installed on a linear injection section of about 3 meters, forming a horizontal convex rail independently, achieving relative independence between the convex rail parameters and the storage ring focusing structure parameters.The impact magnet is a magnet with an empty core current plate structure, used to change the trajectory of the electron beam for injection and extraction. In order to deflect the beam e: 24

Polymer magnetic compounds Polymer magnetic compounds are one of the materials that endow the traditional applications of magnetism and polymers with new meanings and content, while continuously exploring new applications of magnetism and polymer polymers (synthetic resins, rubber). The early magnetic materials were derived from natural magnetite, which was later sintered or cast by Magnetite (ferrite). Now there are three kinds of magnetic materials commonly used in industry, namely ferrite magnets, rare earth magnets and Alnico magnetsTheir disadvantages are both hard and brittle, and poor processability. In order to overcome these defects, polymer magnetic materials made by mixing magnetic particles in plastic or rubber have emerged. The composite polymer magnetic compounds made in this way have attracted increasing attention due to their light weight, easy processing into products with high dimensional accuracy and complex shapes, and the ability to form integrated with other components.: 24
