Spodumene and Hexagonite Chemical Formula
While comparing Spodumene and Hexagonite 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 Spodumene and Hexagonite chemical formula.
- Chemical formula of Spodumene- LiAlSi2O6
- Chemical formula of Hexagonite- Ca 2Mg 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
Spodumene and Hexagonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spodumene and Hexagonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spodumene and Hexagonite Optical Properties during the identification of gemstone. Specific gravity of Spodumene is 2.98-3.03 whereas that of Hexagonite is 2.98-3.03.
