Lavrovite and Biotite Physical Properties

Lavrovite and Biotite Chemical Formula

While comparing Lavrovite 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 Lavrovite and Biotite chemical formula.

• Chemical formula of Lavrovite- NaCa2(Fe2+,Mg)4Si7AlO22(OH)2
• Chemical formula of Biotite- K(Mg,Fe++)3[AlSi3O10(OH,F)2

Lavrovite and Biotite Specific Gravity

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