Hematite and Bornite Physical Properties

Hematite and Bornite Chemical Formula

While comparing Hematite and Bornite 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 Bornite chemical formula.

• Chemical formula of Hematite- Fe 2O 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Bornite- Cu5FeS4

Hematite and Bornite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hematite and Bornite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hematite and Bornite Optical Properties during the identification of gemstone. Specific gravity of Hematite is 5.06-5.08 whereas that of Bornite is 5.06-5.08.
