Austinite and Scorzalite Chemical Formula
While comparing Austinite and Scorzalite 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 Austinite and Scorzalite chemical formula.
- Chemical formula of Austinite- CaZn(AsO4)(OH)
- Chemical formula of Scorzalite- (Fe2+ ,Mg)Al 2(PO 4) 2(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006)
Austinite and Scorzalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Austinite and Scorzalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Austinite and Scorzalite Optical Properties during the identification of gemstone. Specific gravity of Austinite is 3.31 whereas that of Scorzalite is 3.31.
