Nepheline and Pyroxmangite Chemical Formula
While comparing Nepheline and Pyroxmangite 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 Nepheline and Pyroxmangite chemical formula.
- Chemical formula of Nepheline- Na 3(Na,K)Al 4Si 4O 16Ulrich Henn and Claudio C.
- Chemical formula of Pyroxmangite- (Fe,Mn) 7Si 7O 21Ulrich Henn and Claudio C.
Nepheline and Pyroxmangite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Nepheline and Pyroxmangite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepheline and Pyroxmangite Optical Properties during the identification of gemstone. Specific gravity of Nepheline is 3.76-3.77 whereas that of Pyroxmangite is 3.76-3.77.
