Sodalite and Cancrinite Chemical Formula
While comparing Sodalite and Cancrinite 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 Cancrinite chemical formula.
- Chemical formula of Sodalite- Na8Al6Si6O24Cl2
- Chemical formula of Cancrinite- Na 2Ca 2Al 6Si 6O 24(CO 3) 2Walter Schumann , Gemstones of the world (2001) More from other references
Sodalite and Cancrinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Cancrinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Cancrinite Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 2.42-2.52 whereas that of Cancrinite is 2.42-2.52.
