Plasma and Polyhalite Physical Properties

Plasma and Polyhalite Chemical Formula

While comparing Plasma and Polyhalite 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 Polyhalite chemical formula.

• Chemical formula of Plasma- Cu9(AsO4)2(OH)10
• Chemical formula of Polyhalite- K2Ca2Mg(SO4)4·2H2O

Plasma and Polyhalite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Plasma and Polyhalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Plasma and Polyhalite Optical Properties during the identification of gemstone. Specific gravity of Plasma is 2.78 whereas that of Polyhalite is 2.78.
