Hanksite and Dravite Chemical Formula
While comparing Hanksite and Dravite 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 Dravite chemical formula.
- Chemical formula of Hanksite- KNa22(SO4)9(CO3)2Cl
- Chemical formula of Dravite- Na(Mg 3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
Hanksite and Dravite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hanksite and Dravite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hanksite and Dravite Optical Properties during the identification of gemstone. Specific gravity of Hanksite is 3.03-3.18 whereas that of Dravite is 3.03-3.18.
