Tektite and Biotite Physical Properties

Tektite and Biotite Chemical Formula

While comparing Tektite 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 Tektite and Biotite chemical formula.

• Chemical formula of Tektite- SiO2, Al2O3, FeO, MgO, CaO, K2O, Na2O
• Chemical formula of Biotite- K(Mg,Fe++)3[AlSi3O10(OH,F)2

Tektite and Biotite Specific Gravity

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