Brucite Mineral Properties:
Brucite [Chemical 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 and belongs to the trigonal crystal system. Single crystals are thick tabular, while common forms are 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%.
Uses of Brucite:
Production of magnesium hydroxide flame retardant; Manufacturing asbestos-free insulation materials; Refractory materials for protective layers in nuclear reactors of nuclear power plants; Coating for magnesium-based welding electrodes; Thermal insulation materials; Inhibitor for fuel combustion corrosion; Filler in the paper industry; Production of lightly calcined magnesia and dead-burned magnesia; Neutralizing agent for acidic wastewater, adsorbent for heavy metals, and flue gas desulfurization.
