Apophyllite KF and Axinite Chemical Formula
While comparing Apophyllite KF and Axinite 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 Axinite chemical formula.
- Chemical formula of Apophyllite KF- (K,Na)Ca4Si8O20(F,OH)•8(H2O)
- Chemical formula of Axinite- (Ca,Fe,Mn,Mg) 3Al 2BSi 4O 15(OH)Walter Schumann , Gemstones of the world (2001) More from other references
Apophyllite KF and Axinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apophyllite KF and Axinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apophyllite KF and Axinite Optical Properties during the identification of gemstone. Specific gravity of Apophyllite KF is 3.26-3.36 whereas that of Axinite is 3.26-3.36.
