Cavansite and Galena Chemical Formula
While comparing Cavansite and Galena 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 Cavansite and Galena chemical formula.
- Chemical formula of Cavansite- Ca(VO)Si4O10•4(H2O)
- Chemical formula of Galena- PbS
Cavansite and Galena Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cavansite and Galena Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cavansite and Galena Optical Properties during the identification of gemstone. Specific gravity of Cavansite is 6.23 whereas that of Galena is 6.23.
