Hanksite and Iolite Chemical Formula
While comparing Hanksite and Iolite 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 Hanksite and Iolite chemical formula.
- Chemical formula of Hanksite- KNa22(SO4)9(CO3)2Cl
- Chemical formula of Iolite- Mg2Al4Si5O18
Hanksite and Iolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hanksite and Iolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hanksite and Iolite Optical Properties during the identification of gemstone. Specific gravity of Hanksite is 2.6-2.7 whereas that of Iolite is 2.6-2.7.
