Sodalite and Tremolite Chemical Formula
While comparing Sodalite and Tremolite 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 Tremolite chemical formula.
- Chemical formula of Sodalite- Na8Al6Si6O24Cl2
- Chemical formula of Tremolite- Ca 2Mg 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
Sodalite and Tremolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Tremolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Tremolite Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 2.95-3.07 whereas that of Tremolite is 2.95-3.07.
