Hibonite and Bytownite Chemical Formula
While comparing Hibonite and Bytownite 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 Bytownite chemical formula.
- Chemical formula of Hibonite- (Ca,Ce)(Al,Ti,Mg)12O19
- Chemical formula of Bytownite- Ca(70-90%)Na(30-10%)(Al,Si)AlSi 2O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
Hibonite and Bytownite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hibonite and Bytownite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hibonite and Bytownite Optical Properties during the identification of gemstone. Specific gravity of Hibonite is 2.72-2.75 whereas that of Bytownite is 2.72-2.75.
