Knowra Brucite Brucite Brucite is a mineral composed of magnesium hydroxide, Mg(OH)₂. It commonly forms white, pale-green, or blue crystals and occurs in altered magnesium-rich rocks.
Magnesium hydroxide : An inorganic compound with formula Mg(OH)₂, occurring naturally as brucite and used in several industrial and medical applications. Brucite is the mineral form of this compound.
Serpentinization : A hydration process that transforms ultramafic rocks into serpentine-bearing assemblages. Brucite can form as a product when water alters magnesium-rich mantle rocks.
Flame retardant : A material or treatment that slows ignition, combustion, or flame spread. Brucite releases water when heated, cooling materials and diluting combustible gases.
Marble : A metamorphic rock composed mainly of recrystallized carbonate minerals, especially calcite or dolomite. Brucite can occur in magnesium-rich marbles altered by heat and fluids.
Gibbsite : An aluminum hydroxide mineral with formula Al(OH)₃ and a layered crystal structure. Its hydroxide layers resemble brucite’s, but aluminum replaces magnesium.
Hydroxide : A chemical group consisting of an oxygen atom bonded to a hydrogen atom, carrying a −1 charge. Hydroxide groups combine with magnesium to make brucite’s chemical formula.
Hydrothermal alteration : Chemical and mineralogical change in rocks caused by circulating heated fluids. Hot fluids can precipitate or alter brucite in magnesium-rich rocks.
Magnesia : Magnesium oxide used in refractory materials, agriculture, and other industrial products. Brucite is a feedstock for magnesia produced by controlled heating.
Serpentinite : A rock composed largely of serpentine-group minerals, formed by hydration of ultramafic rocks. Brucite commonly accompanies serpentine minerals in altered ultramafic rocks.
Portlandite : A calcium hydroxide mineral with formula Ca(OH)₂. Portlandite shares brucite’s hydroxide chemistry but contains calcium instead of magnesium.
