Erythrite and Brucite Physical Properties

Erythrite and Brucite Chemical Formula

While comparing Erythrite and Brucite 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 Erythrite and Brucite chemical formula.

• Chemical formula of Erythrite- Co3(AsO4)2•8(H2O)
• Chemical formula of Brucite- Mg(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)

Erythrite and Brucite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Erythrite and Brucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Erythrite and Brucite Optical Properties during the identification of gemstone. Specific gravity of Erythrite is 2.39 whereas that of Brucite is 2.39.
