Cavansite and Afghanite Chemical Formula
While comparing Cavansite and Afghanite 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 Afghanite chemical formula.
- Chemical formula of Cavansite- Ca(VO)Si4O10•4(H2O)
- Chemical formula of Afghanite- (Na,Ca,K) 8(Si,Al) 12O 24(SO 4,Cl,CO 3) 3(H 2O)Arthur Thomas , Gemstones (2009)
Cavansite and Afghanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cavansite and Afghanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cavansite and Afghanite Optical Properties during the identification of gemstone. Specific gravity of Cavansite is 2.55-2.65 whereas that of Afghanite is 2.55-2.65.
