Cavansite and Povondraite Chemical Formula
While comparing Cavansite and Povondraite 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 Povondraite chemical formula.
- Chemical formula of Cavansite- Ca(VO)Si4O10•4(H2O)
- Chemical formula of Povondraite- NaFe3+3Fe3+6(BO 3) 3Si 6O 18(O,OH) 4Anthony et al , Handbook of Mineralogy (2001)
Cavansite and Povondraite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cavansite and Povondraite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cavansite and Povondraite Optical Properties during the identification of gemstone. Specific gravity of Cavansite is 3.26 whereas that of Povondraite is 3.26.
