Austinite and Azurmalachite Chemical Formula
While comparing Austinite and Azurmalachite 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 Azurmalachite chemical formula.
- Chemical formula of Austinite- CaZn(AsO4)(OH)
- Chemical formula of Azurmalachite- (Cu) 3(OH) 2(CO 3) 2 + Cu 2(CO 3)(OH) 2Gemdat.org , Management Team (2012)
Austinite and Azurmalachite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Austinite and Azurmalachite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Austinite and Azurmalachite Optical Properties during the identification of gemstone. Specific gravity of Austinite is 3.70-3.95 whereas that of Azurmalachite is 3.70-3.95.
