Chromite and Edenite Chemical Formula
While comparing Chromite and Edenite 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 Chromite and Edenite chemical formula.
- Chemical formula of Chromite- Fe++Cr2O4
- Chemical formula of Edenite- NaCa2Mg5Si7AlO22(OH)2
Chromite and Edenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chromite and Edenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chromite and Edenite Optical Properties during the identification of gemstone. Specific gravity of Chromite is 3.05-3.37 whereas that of Edenite is 3.05-3.37.
