Chromite and Thulite Chemical Formula
While comparing Chromite and Thulite 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 Thulite chemical formula.
- Chemical formula of Chromite- Fe++Cr2O4
- Chemical formula of Thulite- Ca2Al3(SiO4)3(OH)
Chromite and Thulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chromite and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chromite and Thulite Optical Properties during the identification of gemstone. Specific gravity of Chromite is 3.1 whereas that of Thulite is 3.1.
