Sodalite and Adamite Chemical Formula
While comparing Sodalite and Adamite 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 Sodalite and Adamite chemical formula.
- Chemical formula of Sodalite- Na8Al6Si6O24Cl2
- Chemical formula of Adamite- Zn 2(AsO 4)(OH)Michael OâDonoghue , Gems, Sixth edition (2006)
Sodalite and Adamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Adamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Adamite Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 4.32-4.48 whereas that of Adamite is 4.32-4.48.
