Mineral uses of brucite

Physical and chemical properties of brucite
The fracture surface of brucite presents glass luster, its cleavage surface has pearl luster, and the luster of fibrous brucite presents silk type; Transparent, with a hardness of 2.5. The fine pieces of brucite have flexibility and a certain degree of 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. The elastic modulus of brucite is 13800mpa, which has 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, Mg and MgO products can be extracted from brucite; The heavy burned magnesia made of 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 magnesia carbon bricks and magnesia chrome bricks are needed; Brucite can also be used to produce light magnesium oxide: developed countries such as Europe and the United States can extract light MgO from low-quality brucite by certain chemical methods for use; At the same time, brucite can also be used to make chemically pure magnesium reagents. Magnesium can be extracted by electric heating and used to make chemically pure magnesium chemicals.
Periclase is synthesized by electrofusion, so as to make special pure products needed by high-tech electronic products. Periclase is obtained by smelting brucite, which has high thermal conductivity and good electrical insulation. At the same time, brucite can also be used as reinforcement material, and fibrous brucite is used as a substitute for chrysotile asbestos in some special fields. Polypropylene can also be used as the matrix to manufacture flame retardants. Brucite is a non-toxic and pollution-free flame retardant because of its good flame retardant effect. Due to the high whiteness of brucite, it can be used in papermaking. In addition, because brucite is dense and rich in color, with good light transmittance and even and delicate texture, it has been processed to form other patterns and shapes, which is quite ornamental.
Formation cause of brucite
Brucite is a mineral altered by low temperature hydrothermal solution in dolomite or serpentine. The crystal structure is layered. The structural layer of the ore is ionic bond, and each layer of the structure can be maintained by phase. The single crystal of brucite presents a thick plate shape, commonly including flake and fiber shape. In addition, it often forms the appearance of periclase.
