Ajoite and Austinite Chemical Formula
While comparing Ajoite and Austinite 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 Ajoite and Austinite chemical formula.
- Chemical formula of Ajoite- (K,Na)3Cu20Al3Si29O76(OH)16•~8(H2O)
- Chemical formula of Austinite- CaZn(AsO4)(OH)
Ajoite and Austinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ajoite and Austinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ajoite and Austinite Optical Properties during the identification of gemstone. Specific gravity of Ajoite is 4.12 whereas that of Austinite is 4.12.
