Austinite and Wardite Chemical Formula
While comparing Austinite and Wardite 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 Wardite chemical formula.
- Chemical formula of Austinite- CaZn(AsO4)(OH)
- Chemical formula of Wardite- NaAl 3(PO 4) 2(OH) 4 · 2H 2OMichael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Austinite and Wardite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Austinite and Wardite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Austinite and Wardite Optical Properties during the identification of gemstone. Specific gravity of Austinite is 2.81 whereas that of Wardite is 2.81.
