Sphene and Austinite Physical Properties

Sphene and Austinite Chemical Formula

While comparing Sphene 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 Sphene and Austinite chemical formula.

• Chemical formula of Sphene- CaTiSiO5
• Chemical formula of Austinite- CaZn(AsO4)(OH)

Sphene and Austinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sphene and Austinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sphene and Austinite Optical Properties during the identification of gemstone. Specific gravity of Sphene is 4.12 whereas that of Austinite is 4.12.
