Iddingsite and Austinite Physical Properties

Iddingsite and Austinite Chemical Formula

While comparing Iddingsite 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 Iddingsite and Austinite chemical formula.

• Chemical formula of Iddingsite- MgO.Fe2O3.3SiO2•4(H2O)
• Chemical formula of Austinite- CaZn(AsO4)(OH)

Iddingsite and Austinite Specific Gravity

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