Nepheline and Copper Chemical Formula

While comparing Nepheline and Copper 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 Copper chemical formula.

  • Chemical formula of Nepheline- Na 3(Na,K)Al 4Si 4O 16Ulrich Henn and Claudio C.
  • Chemical formula of Copper- Cu

Nepheline and Copper Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nepheline and Copper Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepheline and Copper Optical Properties during the identification of gemstone. Specific gravity of Nepheline is Not Available whereas that of Copper is Not Available.
