Plasma and Ettringite Physical Properties

Plasma and Ettringite Chemical Formula

While comparing Plasma and Ettringite 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 Ettringite chemical formula.

• Chemical formula of Plasma- Cu9(AsO4)2(OH)10
• Chemical formula of Ettringite- Ca 6Al 2(SO 4) 3(OH) 12 26H 2OMichael O’Donoghue , Gems, Sixth Edition (2006)

Plasma and Ettringite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Plasma and Ettringite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Plasma and Ettringite Optical Properties during the identification of gemstone. Specific gravity of Plasma is 1.77 whereas that of Ettringite is 1.77.
