Beudantite and Faustite Chemical Formula
While comparing Beudantite and Faustite 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 Beudantite and Faustite chemical formula.
- Chemical formula of Beudantite- PbFe+++3(AsO4)(SO4)(OH)6
- Chemical formula of Faustite- (Zn,Cu)Al 6(PO 4) 4(OH) 8 · 4H 2OMichael OâDonoghue , Gems, Sixth Edition (2006)
Beudantite and Faustite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Beudantite and Faustite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Beudantite and Faustite Optical Properties during the identification of gemstone. Specific gravity of Beudantite is 2.9 whereas that of Faustite is 2.9.
