Gibbsite and Barite Chemical Formula

While comparing Gibbsite and Barite 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 Gibbsite and Barite chemical formula.

  • Chemical formula of Gibbsite- Al(OH)3
  • Chemical formula of Barite- BaSO4

Gibbsite and Barite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gibbsite and Barite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Barite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 4.48 whereas that of Barite is 4.48.
