Nepouite and Goethite Physical Properties

Nepouite and Goethite Chemical Formula

While comparing Nepouite and Goethite 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 Nepouite and Goethite chemical formula.

• Chemical formula of Nepouite- Ni3(Si2O5)(OH)4
• Chemical formula of Goethite- FeO(OH)Arthur Thomas , Gemstones (2009)

Nepouite and Goethite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nepouite and Goethite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepouite and Goethite Optical Properties during the identification of gemstone. Specific gravity of Nepouite is 4.27-4.29 whereas that of Goethite is 4.27-4.29.
