Biotite and Leucite Physical Properties

Biotite and Leucite Chemical Formula

While comparing Biotite and Leucite 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 Leucite chemical formula.

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

Biotite and Leucite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Biotite and Leucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Biotite and Leucite Optical Properties during the identification of gemstone. Specific gravity of Biotite is 2.45-2.50 whereas that of Leucite is 2.45-2.50.
