Biotite and Analcime Chemical Formula
While comparing Biotite and Analcime 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 Analcime chemical formula.
- Chemical formula of Biotite- K(Mg,Fe++)3[AlSi3O10(OH,F)2
- Chemical formula of Analcime- NaAlSi 2O 6 · H 2OMichael OâDonoghue , Gems, Sixth edition (2006) More from other references
Biotite and Analcime Specific Gravity
Another important criteria for qualitative analysis of gemstones is Biotite and Analcime Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Biotite and Analcime Optical Properties during the identification of gemstone. Specific gravity of Biotite is 2.24-2.29 whereas that of Analcime is 2.24-2.29.
