Pyroxmangite and Biotite Physical Properties

Pyroxmangite and Biotite Chemical Formula

While comparing Pyroxmangite 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 Pyroxmangite and Biotite chemical formula.

• Chemical formula of Pyroxmangite- (Fe,Mn) 7Si 7O 21Ulrich Henn and Claudio C.
• Chemical formula of Biotite- K(Mg,Fe++)3[AlSi3O10(OH,F)2

Pyroxmangite and Biotite Specific Gravity

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