Lepidocrocite and Biotite Physical Properties

Lepidocrocite and Biotite Chemical Formula

While comparing Lepidocrocite 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 Lepidocrocite and Biotite chemical formula.

• Chemical formula of Lepidocrocite- FeO(OH)
• Chemical formula of Biotite- K(Mg,Fe++)3[AlSi3O10(OH,F)2

Lepidocrocite and Biotite Specific Gravity

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