Gibbsite and Augite Chemical Formula
While comparing Gibbsite and Augite 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 Augite chemical formula.
- Chemical formula of Gibbsite- Al(OH)3
- Chemical formula of Augite- (Ca,Na)(Mg,Fe,Al,Ti)(Si,Al) 2O 6Anthony et al , Handbook of mineralogy (2001)
Gibbsite and Augite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gibbsite and Augite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Augite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 3.19-3.56 whereas that of Augite is 3.19-3.56.
