Brucite and Sodalite Physical Properties

Brucite and Sodalite Chemical Formula

While comparing Brucite and Sodalite 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 Sodalite chemical formula.

• Chemical formula of Sodalite- Na₈Al₆Si₆O₂₄Cl₂

Brucite and Sodalite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Brucite and Sodalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brucite and Sodalite Optical Properties during the identification of gemstone. Specific gravity of Brucite is 2.15-2.40 whereas that of Sodalite is 2.15-2.40.
