Hibonite and Rossmanite Chemical Formula
While comparing Hibonite and Rossmanite 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 Hibonite and Rossmanite chemical formula.
- Chemical formula of Hibonite- (Ca,Ce)(Al,Ti,Mg)12O19
- Chemical formula of Rossmanite- ◻(LiAl 2)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
Hibonite and Rossmanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hibonite and Rossmanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hibonite and Rossmanite Optical Properties during the identification of gemstone. Specific gravity of Hibonite is 3 whereas that of Rossmanite is 3.
