Agrellite and Elbaite Chemical Formula
While comparing Agrellite and Elbaite 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 Agrellite and Elbaite chemical formula.
- Chemical formula of Agrellite- NaCa2Si4O10F
- Chemical formula of Elbaite- Na(Li 1.5Al 1.5)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012) More from other references
Agrellite and Elbaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Agrellite and Elbaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Agrellite and Elbaite Optical Properties during the identification of gemstone. Specific gravity of Agrellite is 2.90-3.10 whereas that of Elbaite is 2.90-3.10.
