Mineral Uses of Brucite

Bischofite is also called oxymagnesite, and its chemical equation is Mg (OH) 2. The hardness of brucite is about 2.5. The common brucite is a flaky aggregate or a fibrous aggregate. We usually call it chrysotile or brucite asbestos. Today, I will tell you about the use of hydromagnesite and the basic information of brucite. I hope you can learn about brucite from the explanations compiled from childhood.
Physical and chemical properties of brucite
The fracture surface of brucite has glass luster, its cleavage surface has pearl luster, and the luster of fibrous brucite is silk like; Transparent, with hardness of 2.5. The fine pieces of brucite have flexibility and a certain degree of flexibility. The whiteness of cut brucite can reach 95%.
Mechanical properties of brucite: the tensile strength of fibrous brucite is about 902MPa, which is a medium strength fiber material. The elastic modulus of brucite is 13800MPa, which has a certain brittleness. It is easy to grind into fine powder. The relative density of brucite powder is 2.39.
Chemical properties: Brucite is the best alkali resistant inorganic fiber naturally formed. It will dissolve in strong acid, and brucite is easy to be eroded under 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. Because of the MgO content in brucite ore and easy decomposition, products such as Mg and MgO can be extracted from brucite; The calcined magnesia made from brucite has the advantages of high density and high refractoriness. Because in the modern iron and steel industry, a large number of magnesia carbon bricks, magnesia chrome bricks and other products are needed; Brucite can also be used to produce light magnesium oxide: developed countries in Europe and America can extract light MgO from low-quality brucite for use by certain chemical methods; At the same time, brucite can also be used to make chemical pure magnesium reagents. Magnesium can be extracted by electric heating to make chemical pure reagents of magnesium compounds.
The periclase is synthesized by electric melting, so as to make the special pure products required by high-tech electronic products. The periclase, which has high thermal conductivity and good electrical insulation, is made from brucite by electric melting. At the same time, brucite can also be used as reinforcement material, and chrysotile brucite can be used as a substitute for chrysotile in some special fields. Polypropylene can also be used as the matrix to produce flame retardant. Brucite has good flame retardant effect, so it is non-toxic and pollution-free flame retardant. Due to its high whiteness, brucite can be used for paper making. In addition, because brucite is dense, rich in color, good in light transmittance, and even in texture, it is processed to form other patterns, which is of great ornamental value.
Formation causes of brucite
Brucite is a mineral formed by low-temperature hydrothermal alteration in dolomite or serpentine. The crystal structure is layered. There are ionic bonds in the structure layer of the ore, and each layer of the structure can be maintained by phase. The single crystal of brucite presents a thick plate shape, which is common in sheet and fiber shape. In addition, it often forms the appearance of periclase.
Well, Xiao Bian's introduction of brucite ends here. I believe you have a certain understanding of the use and properties of brucite through this introduction.
