Chromite and Gibbsite Chemical Formula

While comparing Chromite and Gibbsite 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 Chromite and Gibbsite chemical formula.

  • Chemical formula of Chromite- Fe++Cr2O4
  • Chemical formula of Gibbsite- Al(OH)3

Chromite and Gibbsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chromite and Gibbsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chromite and Gibbsite Optical Properties during the identification of gemstone. Specific gravity of Chromite is 2.35 whereas that of Gibbsite is 2.35.
