Composition of Brucite Brucite is natural magnesium hydroxide, also known as hydrated magnesia. Melting point (dehydration) 340 C, relative density: 2.39, hardness: 2.5, crystal structure: six crystal systems, relative molecular mass: 58.32, solubility: 0.009 g / L. Brucite has a simple chemical composition and its molecular formula is Mg(OH)2. Brucite is a rare high-magnesium mineral in nature. Its theoretical chemical composition is MgO 69.12% and H2O 30.55%. It is often found in brucites produced in nature. Impurities such as Fe, Mn, Zn, Ni, etc., these impurities exist as a homogeneous image, forming a series of continuous or discontinuous solid solution, constituent endmembers: iron brucite (including FeO 10%), manganese brucite (containing MnO 18%), zinc brucite (including ZnO 4%), nickel brucite (including NiO 2.5%). The associated minerals of brucite are serpentine, calcite, dolomite, magnesite, magnesium silicate mineral, periclase, diopside and talc. Use of brucite Brucite is an industrial mineral with special value due to its high content of useful components, low content of harmful impurities, and its unique physicochemical properties, which are different from other types of magnesium-containing mineral raw materials. The main uses of brucite is as below: 1.Flame retardant additives in rubber, plastic and fiber 2.� Flue gas desulfurization 3.Aluminum composite panel 4.Paper industry 5.Agriculture and fertilizer uses 6.Environmental protection field (Wastewater treatment) 7.Magnesia high temperature refractory 8.Fireproof coating 9.Neutralize the treatment agent and adjust the pH value
Large crystal fused magnesia production process: Large crystal fused magnesia is mainly made of 91%-92% magnesium oxide and 0mm-3mm magnesium oxide particles, which are melted in an electric arc furnace. The product has high purity, large crystal grains, compact structure, strong slag resistance and good thermal shock stability. raw material. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components, etc. Features of large crystal fused magnesia: high purity, large melting crystal grains, high point structure, dense structure; good thermal shock stability; good high temperature flexural strength; good slag resistance and corrosion resistance; thermal conductivity Strong performance and high insulation. Product use of large crystal fused magnesia: large crystal fused magnesia is used as a refractory lining for steelmaking furnaces, and is a high-quality and high-grade basic refractory raw material for making refractory bricks and unshaped refractories; it can also be used as a filler for making Thermocouples and thermal insulation materials (household appliances, etc.); can also be used in ceramic raw materials and sintering aids as well as metallurgy, building materials, chemicals, national defense, medical equipment, etc.
Caustic Calcined Magnesite is also known as magnesia, bitter earth powder, light burnt magnesium powder, and its main component is mainly magnesium oxide. The natural magnesite ore is used as the main raw material, and is calcined at a temperature of 800 to 850 ° C. The color of the product is pink, yellow and white.   Light burnt magnesium mainly manufactures cementitious materials, such as magnesium-containing cement. Thermal insulation and sound insulation construction materials, can also be used as ceramic raw materials. After chemical treatment of light burnt magnesium, can be made into a variety of magnesium salts, used as medicine. Rubber. Raw materials such as man-made fiber, papermaking, etc. Reburning magnesium. Most of the refractory materials used for metallurgy are used in the manufacture of magnesia bricks. chrome-magnesia bricks. Magnesia. Metallurgical powder. Electro-fused magnesium oxide is mainly used for smelting special alloy steel. Medium and high frequency induction furnace lining of non-ferrous metals and precious metals. Magnesium bismuth. It can also be used as high temperature electrical insulation material.

Brucite is the mineral form of magnesium hydroxide, with the chemical formula Mg(OH)2. It is a common alteration product of periclase in marble; a low-temperature hydrothermal vein mineral in metamorphosed limestones andchlorite schists; and formed during serpentinization of dunites. Brucite is often found in association. magnesium ore - natural brucite pirce Brucite is also called as magnesium hydroxide. The molecular formula is Mg(OH)2, with theoretical values of MgO 69%,H2O 31%. It usually shows white, grey and light greenish yellow in color. Whiteness is 80-85, Moh hardness is 2.5, and the relative density is 2.3-2.6. Brucite is a fibrous magnesium hydroxide rarely at home and abroad. It is white color and easy to split. Nowadays brucite becomes ideal substitute for asbestos due to excellent performance and competitive price.
Brucite : chemical formula is Mg(OH)2 (Magnesium Hydroxide/Hydrate) Details: white hexagonal crystal or amorphous powder. Water solution is alkaline, the Relative density is2.36g/ cubic meters. It can solute in acid and ammonium salt, almost insoluble in water and alcohol. In water solubility degree (18 °C)is 0009g / 100g . Easy to absorb carbon dioxide in the air. At 350 °C,decomposed into magnesium oxide and water. Above 500 °C, lose water into magnesium oxide. Application: Flame retardant, refractory, agriculture, desulfurization, water treatment, etc.
