Hanksite and Lazurite Chemical Formula
While comparing Hanksite and Lazurite 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 Lazurite chemical formula.
- Chemical formula of Hanksite- KNa22(SO4)9(CO3)2Cl
- Chemical formula of Lazurite- (Na,Ca) 8Al 6Si 6O 24(SO 4,S,Cl) 2Ulrich Henn and Claudio C.
Hanksite and Lazurite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hanksite and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hanksite and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Hanksite is 2.75 whereas that of Lazurite is 2.75.
