Rhyolite and Hematite Physical Properties

Rhyolite and Hematite Chemical Formula

While comparing Rhyolite and Hematite 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 Rhyolite and Hematite chemical formula.

• Chemical formula of Rhyolite- 70% SiO2, Al2O3, Na2O, K2O
• Chemical formula of Hematite- Fe 2O 3Arthur Thomas , Gemstones (2009)

Rhyolite and Hematite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rhyolite and Hematite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhyolite and Hematite Optical Properties during the identification of gemstone. Specific gravity of Rhyolite is 5.00-5.30 whereas that of Hematite is 5.00-5.30.
