Nepheline and Humite Chemical Formula

While comparing Nepheline and Humite 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 Humite chemical formula.

  • Chemical formula of Nepheline- Na 3(Na,K)Al 4Si 4O 16Ulrich Henn and Claudio C.
  • Chemical formula of Humite- (Mg,Fe2+ ) 7(SiO 4) 3(F,OH) 2Anthony et al , Handbook of mineralogy (2001)

Nepheline and Humite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nepheline and Humite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepheline and Humite Optical Properties during the identification of gemstone. Specific gravity of Nepheline is 3.20-3.32 whereas that of Humite is 3.20-3.32.
