Hematite and Augite Physical Properties

Hematite and Augite Chemical Formula

While comparing Hematite and Augite 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 Hematite and Augite chemical formula.

• Chemical formula of Augite- (Ca,Na)(Mg,Fe,Al,Ti)(Si,Al) 2O 6Anthony et al , Handbook of mineralogy (2001)

Hematite and Augite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hematite and Augite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hematite and Augite Optical Properties during the identification of gemstone. Specific gravity of Hematite is 3.19-3.56 whereas that of Augite is 3.19-3.56.
