Augite and Nepheline Physical Properties

Augite and Nepheline Chemical Formula

While comparing Augite and Nepheline 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 Augite and Nepheline chemical formula.

• Chemical formula of Augite- (Ca,Na)(Mg,Fe,Al,Ti)(Si,Al) 2O 6Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Nepheline- Na 3(Na,K)Al 4Si 4O 16Ulrich Henn and Claudio C.

Augite and Nepheline Specific Gravity

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