Norbergite and Austinite Physical Properties

Norbergite and Austinite Chemical Formula

While comparing Norbergite 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 Norbergite and Austinite chemical formula.

• Chemical formula of Norbergite- Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001)
• Chemical formula of Austinite- CaZn(AsO4)(OH)

Norbergite and Austinite Specific Gravity

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