Biotite and Scorzalite Chemical Formula
While comparing Biotite and Scorzalite 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 Scorzalite chemical formula.
- Chemical formula of Biotite- K(Mg,Fe++)3[AlSi3O10(OH,F)2
- Chemical formula of Scorzalite- (Fe2+ ,Mg)Al 2(PO 4) 2(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006)
Biotite and Scorzalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Biotite and Scorzalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Biotite and Scorzalite Optical Properties during the identification of gemstone. Specific gravity of Biotite is 3.31 whereas that of Scorzalite is 3.31.
