Leucite and Biotite Physical Properties

Leucite and Biotite Chemical Formula

While comparing Leucite and Biotite 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 Leucite and Biotite chemical formula.

• Chemical formula of Leucite- KAlSi 2O 6Michael O’Donoghue , Gems, Sixth Edition (2006) More from other references
• Chemical formula of Biotite- K(Mg,Fe++)3[AlSi3O10(OH,F)2

Leucite and Biotite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Leucite and Biotite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Leucite and Biotite Optical Properties during the identification of gemstone. Specific gravity of Leucite is 2.7-3.3 whereas that of Biotite is 2.7-3.3.
