Brucite Mineral Characteristics:
Brucite [Molecular formula: Mg(OH)₂] is a natural mineral with high magnesium content and rich in crystalline water. It begins to decompose into MgO and releases a large amount of water vapor when heated to 340°C. [Crystal Chemistry] Theoretical composition: MgO 69.12%, H₂O 30.88%;
Often contains impurities such as Fe, Mn, Zn, and Ni in isomorphic forms. It has a layered structure, trigonal crystal system, with single crystals appearing as thick plates; commonly found as flaky aggregates;
Fibrous aggregates are known as nemalite. Brucite has a Mohs hardness of 2.5, a density of 2.3-2.6, and a whiteness of over 90%.
Brucite Applications:
Production of magnesium hydroxide flame retardants;
Manufacturing asbestos-free insulation materials;
Protective layers for nuclear reactors in nuclear power plants as refractory materials;
Magnesium-based fluxes and coatings for welding electrodes;
Thermal insulation materials;
Inhibitors for fuel combustion corrosion;
Fillers in the paper industry;
Production of light-burned magnesia and dead-burned magnesia;
Neutralizing agents for acidic wastewater, adsorption of heavy metals, and flue gas desulfurization;
