Gibbsite and Cacoxenite Chemical Formula
While comparing Gibbsite and Cacoxenite 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 Cacoxenite chemical formula.
- Chemical formula of Gibbsite- Al(OH)3
- Chemical formula of Cacoxenite- (Fe+++,Al)25(PO4)17O6(OH)12•75(H2O)
Gibbsite and Cacoxenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gibbsite and Cacoxenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Cacoxenite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 2.2-2.6 whereas that of Cacoxenite is 2.2-2.6.
