Cavansite and Pectolite Chemical Formula
While comparing Cavansite and Pectolite 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 Pectolite chemical formula.
- Chemical formula of Cavansite- Ca(VO)Si4O10•4(H2O)
- Chemical formula of Pectolite- Ca 2NaHSi 3O 9Ulrich Henn and Claudio C.
Cavansite and Pectolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cavansite and Pectolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cavansite and Pectolite Optical Properties during the identification of gemstone. Specific gravity of Cavansite is 2.74-2.90 whereas that of Pectolite is 2.74-2.90.
