Gibbsite and Binghamite Chemical Formula
While comparing Gibbsite and Binghamite 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 Binghamite chemical formula.
- Chemical formula of Gibbsite- Al(OH)3
- Chemical formula of Binghamite- SiO 2Arthur Thomas , Gemstones (2009)
Gibbsite and Binghamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gibbsite and Binghamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Binghamite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 2.55-2.70 whereas that of Binghamite is 2.55-2.70.
