Mineral uses of brucite

Brucite manufacturer will answer for you:


Physical and chemical properties of brucite


The fracture of brucite presents glass luster, its cleavage surface has pearl luster, and the luster of fibrous brucite presents silk type; Transparent, hardness 2.5. The fine pieces of brucite have flexibility and certain flexibility. The whiteness of sliced brucite can reach 95%.


Mechanical properties of brucite: the tensile strength of brucite is about 902mpa, which is a medium strength fiber material. Brucite has an elastic modulus of 13800mpa and has a certain brittleness. It is easy to grind into fine-grained powder. The relative density of brucite powder is 2.39.


Chemical properties: brucite is the best alkali resistant inorganic fiber formed naturally. It will dissolve in strong acid, and brucite is easy to be eroded in humid environment.


Application of brucite


Application in industrial field: brucite can be used to extract magnesium and magnesium oxide, and brucite can be used to extract mg and MgO. Due to the MgO content in brucite ore and easy decomposition, products such as Mg and MgO can be extracted from brucite; The calcined magnesia prepared from brucite has the advantages of high density and high fire resistance. Because in the modern iron and steel industry, a large number of products such as magnesium carbon brick and magnesium chromium brick are needed; Brucite can also be used to manufacture light magnesium oxide: developed countries such as Europe and America can extract light MgO from low-quality brucite by certain chemical methods; At the same time, brucite can also be used to make chemical pure magnesium reagent. Magnesium can be extracted by electric heating to make chemical pure reagent of magnesium compounds.


Periclase is synthesized by electrofusion, so as to make special pure products for high-tech electronic products. Periclase is prepared from brucite by electrofusion, which has high thermal conductivity and good electrical insulation. At the same time, brucite can also be used as reinforcement material. Brucite is used as a substitute for chrysotile asbestos in some special fields. The flame retardant can also be made with polypropylene as the matrix. Brucite is a non-toxic and pollution-free flame retardant because it has good flame retardant effect. Due to the high whiteness of brucite, it can be used in papermaking. In addition, because brucite is dense, rich in color, good light transmittance, uniform and fine texture, it is processed to form other patterns, which is of great ornamental value.


Formation of brucite


Brucite is a low-temperature hydrothermal alteration mineral in dolomite or serpentine. The crystal structure is layered, the structural layer of the ore is ion bond, and each layer of the structure can be maintained by phase. The single crystal of brucite presents a thick plate shape, commonly flake and fibrous. In addition, it often forms the appearance of periclase.


Well, this is the end of Xiaobian's introduction to brucite. I believe you have a certain understanding of the use and properties of brucite through the introduction of this article.
