Pyroxmangite and Norbergite Physical Properties

Pyroxmangite and Norbergite Chemical Formula

While comparing Pyroxmangite and Norbergite 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 Pyroxmangite and Norbergite chemical formula.

• Chemical formula of Pyroxmangite- (Fe,Mn) 7Si 7O 21Ulrich Henn and Claudio C.
• Chemical formula of Norbergite- Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001)

Pyroxmangite and Norbergite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyroxmangite and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyroxmangite and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Pyroxmangite is 3.177 whereas that of Norbergite is 3.177.
