Austinite and Papagoite Chemical Formula
While comparing Austinite and Papagoite 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 Papagoite chemical formula.
- Chemical formula of Austinite- CaZn(AsO4)(OH)
- Chemical formula of Papagoite- CaCuAlSi 2O 6(OH) 3Michael OâDonoghue , Gems, Sixth Edition (2006)
Austinite and Papagoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Austinite and Papagoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Austinite and Papagoite Optical Properties during the identification of gemstone. Specific gravity of Austinite is 3.25 whereas that of Papagoite is 3.25.
