Apophyllite KF and Omphacite Chemical Formula
While comparing Apophyllite KF and Omphacite 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 Apophyllite KF and Omphacite chemical formula.
- Chemical formula of Apophyllite KF- (K,Na)Ca4Si8O20(F,OH)•8(H2O)
- Chemical formula of Omphacite- (Ca,Na)(Mg,Fe,Al)Si 2O 6Anthony et al , Handbook of Mineralogy (2001)
Apophyllite KF and Omphacite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apophyllite KF and Omphacite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apophyllite KF and Omphacite Optical Properties during the identification of gemstone. Specific gravity of Apophyllite KF is 3.16-3.43 whereas that of Omphacite is 3.16-3.43.
