Andesine and Foitite Chemical Formula
While comparing Andesine and Foitite 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 Andesine and Foitite chemical formula.
- Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
- Chemical formula of Foitite- Na x[Fe2+2(Al,Fe3+ )]Al 6(BO 3) 3Si 6O 18(OH) 4Anthony et al , Handbook of mineralogy (2001)
Andesine and Foitite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andesine and Foitite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andesine and Foitite Optical Properties during the identification of gemstone. Specific gravity of Andesine is 3.17 whereas that of Foitite is 3.17.
