Biotite and Ekanite Chemical Formula
While comparing Biotite and Ekanite 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 Biotite and Ekanite chemical formula.
- Chemical formula of Biotite- K(Mg,Fe++)3[AlSi3O10(OH,F)2
- Chemical formula of Ekanite- ThCa 2Si 8O 20Walter Schumann , Gemstones of the world (2001) More from other references
Biotite and Ekanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Biotite and Ekanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Biotite and Ekanite Optical Properties during the identification of gemstone. Specific gravity of Biotite is 3.28-3.32 whereas that of Ekanite is 3.28-3.32.
