Plasma and Afghanite Physical Properties

Plasma and Afghanite Chemical Formula

While comparing Plasma and Afghanite 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 Afghanite chemical formula.

• Chemical formula of Plasma- Cu9(AsO4)2(OH)10
• Chemical formula of Afghanite- (Na,Ca,K) 8(Si,Al) 12O 24(SO 4,Cl,CO 3) 3(H 2O)Arthur Thomas , Gemstones (2009)

Plasma and Afghanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Plasma and Afghanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Plasma and Afghanite Optical Properties during the identification of gemstone. Specific gravity of Plasma is 2.55-2.65 whereas that of Afghanite is 2.55-2.65.
