Hibonite and Nepheline Chemical Formula
While comparing Hibonite 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 Hibonite and Nepheline chemical formula.
- Chemical formula of Hibonite- (Ca,Ce)(Al,Ti,Mg)12O19
- Chemical formula of Nepheline- Na 3(Na,K)Al 4Si 4O 16Ulrich Henn and Claudio C.
Hibonite and Nepheline Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hibonite and Nepheline Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hibonite and Nepheline Optical Properties during the identification of gemstone. Specific gravity of Hibonite is 2.55-2.65 whereas that of Nepheline is 2.55-2.65.
