Plasma and Biotite Physical Properties

Plasma and Biotite Chemical Formula

While comparing Plasma 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 Plasma and Biotite chemical formula.

• Chemical formula of Plasma- Cu9(AsO4)2(OH)10
• Chemical formula of Biotite- K(Mg,Fe++)3[AlSi3O10(OH,F)2

Plasma and Biotite Specific Gravity

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