Brucite is a mineral that belongs to the group of layered hydroxides. It has the chemical formula Mg(OH)2, indicating that it consists of magnesium (Mg) and hydroxide (OH) ions. Brucite crystals have a distinct hexagonal or platy crystal structure and often occur as tabular or foliated aggregates. The color of brucite crystals can vary from white to pale green, and they have a pearly or vitreous luster.

Brucite is typically found in magnesium-rich rocks and is formed through hydrothermal or metamorphic processes. It commonly occurs as a secondary mineral in limestone, dolomite, and serpentinite deposits. 

Brucite is also of interest for its industrial applications. It is used in various industries, such as refractories, flame retardants, environmental remediation, and as a source of magnesium in the production of magnesium compounds.
