What are the industrial fields

Raw materials for extracting Mg and MgO: Mg and MgO are extracted with brucite, which has high MgO content and few impurities; Low decomposition temperature; Volatiles produced during heating are non-toxic and harmless, so products such as Mg and MgO can be extracted from brucite. Burned magnesia: mainly used to produce magnesia refractories. Modern iron and steel industry needs a large number of magnesia-carbon bricks and magnesia-chrome bricks. The amount of this kind of MgO has exceeded 1/2 of its output. The reburning magnesia made from brucite has the advantages of high density (> 3.55 g/cm3), high fire resistance (> 2800℃), high chemical inertness and high thermal shock stability. Light MgO: America, Russia, Canada, Britain and other countries use chemical methods to extract light MgO from low-grade brucite rock. Fused periclase: an ultra-pure product required for high-tech electronic products. The periclase aggregate made from brucite by electrofusion has high thermal conductivity and good electrical insulation, and the service life of the product is increased by 2-3 times. Chemically pure magnesium reagent: using electrothermal method, metal magnesium can be extracted to prepare chemically pure reagents such as MgCl2, MgSO4 and Mg(NO3)2. Reinforcing material: Fiberglass can be used as a substitute for chrysotile asbestos in some fields. Used in middle-grade thermal insulation materials such as microporous calcium silicate and calcium silicate board. The basic formula is diatomite lime slurry, sodium silicate fiber brucite. The fiber content is 8-10%. The product has high whiteness, beautiful appearance and low bulk density. Flame retardant: The experiment of making flame retardant based on polypropylene shows that brucite has good flame retardant effect and is an ideal non-toxic, smokeless, pollution-free and high-temperature flame retardant. At the same time, it can enhance the filler. Paper filler: brucite has high whiteness, good stripping property, strong adhesion and poor water absorption. It can be used as paper-making filler with calcite, which can change the paper-making process from acid method to alkali method and reduce the pollution of pulp water. Arts and crafts: the dense block of brucite is rich in color, uniform in texture, good in transparency, delicate and smooth; It often forms natural stripes and patterns with other minerals or varieties, and has ornamental value. Therefore, it can be carved into handicrafts.
