Topaz and Hanksite Chemical Formula
While comparing Topaz and Hanksite 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 Topaz and Hanksite chemical formula.
- Chemical formula of Topaz- Al2SiO4(F,OH)2
- Chemical formula of Hanksite- KNa22(SO4)9(CO3)2Cl
Topaz and Hanksite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Topaz and Hanksite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Topaz and Hanksite Optical Properties during the identification of gemstone. Specific gravity of Topaz is 2.562 whereas that of Hanksite is 2.562.
