[Chemical composition] often contains elements such as Mg, Mn, Ti, V, and Cr. Wherein Mg 2+, Mn 2+ isomorphic substitution Fe 2+ magnet ore ingredients. The content of Ti in magnetite reflects the cause of magnetite more sensitively: the magnetite of magma formation has the highest Ti content, and often forms titanium magnetite. The composition of TiO 2 can reach 12%-16%; The magnetite of the genesis and hydrothermal genesis has a significant decrease in the content of Ti in the composition; the magnetite deposits the metamorphism, and the content of Ti is the lowest. The V 3+ isomorphism replaces Fe 3+ in magnetite to form vanadium magnetite Fe 2+ (Fe 3+ , V 3+ ) 2 O 4 , and its V 2 O 3 content can reach 88%. Like in the same series, chromite component in the Cr 2 O 3 up to 12% magnetite chromite quality class. [crystal structure] equiaxed crystal system; [Form] Single crystal is octahedral {111} (Fig. Y-25), and less is rhombohedral dodecagonal {110}. Stripes are often present in the long diagonal direction on the rhombic dodecahedron. The twin crystal is in contact with the twin crystal according to the spinel law (111). The aggregates often form dense blocks and granules. Figure Y-25 Magnetite crystal aggregate [Physical properties] iron black; black streak; semi-metallic luster; opaque. No cleavage; sometimes with {111} split. Hardness 6. The relative density is 5.20. Crisp. Strong magnetic. [genesis and occurrence] are mainly formed in endogenous and metamorphic effects. It is often used as a secondary mineral of magmatic rocks. In addition, it is a magma-forming iron deposit, a contact iron ore deposit, a gasification-high temperature rare earth iron deposit, a sedimentary metamorphic iron deposit, and a series of volcanic-related iron deposits. The main iron mineral in the. It is also common in sand mines because of its good stability. The famous producing areas of magnetite in China include: Panzhihua (Magma-forming iron deposit) in Sichuan, Anshan (sedimentary metamorphic iron deposit) in Liaoning, and Daye (contact iron ore deposit) in Hubei. [identification characteristics] With its crystal form, black streaks and ferromagnetism can be distinguished from similar minerals such as hematite and chromite. [Main use] is one of the most important iron ore mineral raw materials. The elements such as V, Ti, and Cr are often used in combination.
Longlived 316 Stainless Steel Shot is made from high quality 316 stainless steel. It has higher quality than 410 or 430 Stainless Steel Shot. It can not only strengthen the surface of parts but also make them have some anti-corrsion ability.
