Sodalite and Hanksite Chemical Formula
While comparing Sodalite and Hanksite 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 Hanksite chemical formula.
- Chemical formula of Sodalite- Na8Al6Si6O24Cl2
- Chemical formula of Hanksite- KNa22(SO4)9(CO3)2Cl
Sodalite and Hanksite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Hanksite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Hanksite Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 2.562 whereas that of Hanksite is 2.562.
