Austinite and Hibschite Physical Properties

Austinite and Hibschite Chemical Formula

While comparing Austinite and Hibschite 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 Hibschite chemical formula.

• Chemical formula of Austinite- CaZn(AsO4)(OH)
• Chemical formula of Hibschite- Ca 3Al 2(SiO 4) 3-x(OH) 4x (x=0.2 to 1.5)Anthony et al , Handbook of mineralogy (2001)

Austinite and Hibschite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Austinite and Hibschite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Austinite and Hibschite Optical Properties during the identification of gemstone. Specific gravity of Austinite is 3.05-3.08 whereas that of Hibschite is 3.05-3.08.
