Carnallite and Gibbsite Physical Properties

Carnallite and Gibbsite Chemical Formula

While comparing Carnallite 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 Carnallite and Gibbsite chemical formula.

• Chemical formula of Carnallite- KMgCl3•6(H2O)
• Chemical formula of Gibbsite- Al(OH)3

Carnallite and Gibbsite Specific Gravity

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