Foitite and Anthophyllite Chemical Formula
While comparing Foitite and Anthophyllite 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 Foitite and Anthophyllite chemical formula.
- 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)
- Chemical formula of Anthophyllite- (Mg,Fe2+ ) 2(Mg,Fe2+ ) 5Si 8O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)
Foitite and Anthophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Foitite and Anthophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Foitite and Anthophyllite Optical Properties during the identification of gemstone. Specific gravity of Foitite is 2.9-3.5 whereas that of Anthophyllite is 2.9-3.5.
