Brucite and Antigorite Physical Properties

Brucite and Antigorite Chemical Formula

While comparing Brucite and Antigorite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Brucite and Antigorite chemical formula.
