Plasma and Sphene Physical Properties

Plasma and Sphene Chemical Formula

While comparing Plasma and Sphene 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 Sphene chemical formula.

• Chemical formula of Plasma- Cu9(AsO4)2(OH)10
• Chemical formula of Sphene- CaTiSiO5

Plasma and Sphene Specific Gravity

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