Sodalite and Oligoclase Chemical Formula
While comparing Sodalite and Oligoclase 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 Oligoclase chemical formula.
- Chemical formula of Sodalite- Na8Al6Si6O24Cl2
- Chemical formula of Oligoclase- Na(90-70%)Ca(10-30%)(Al,Si)AlSi 2O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
Sodalite and Oligoclase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Oligoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Oligoclase Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 2.62-2.67 whereas that of Oligoclase is 2.62-2.67.
