Spinel and Liddicoatite Chemical Formula
While comparing Spinel and Liddicoatite 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 Spinel and Liddicoatite chemical formula.
- Chemical formula of Spinel- MgAl2O4
- Chemical formula of Liddicoatite- Ca(Li 2Al)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
Spinel and Liddicoatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spinel and Liddicoatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spinel and Liddicoatite Optical Properties during the identification of gemstone. Specific gravity of Spinel is 3.02 whereas that of Liddicoatite is 3.02.
