Hibonite and Thulite Chemical Formula
While comparing Hibonite and Thulite 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 Thulite chemical formula.
- Chemical formula of Hibonite- (Ca,Ce)(Al,Ti,Mg)12O19
- Chemical formula of Thulite- Ca2Al3(SiO4)3(OH)
Hibonite and Thulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hibonite and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hibonite and Thulite Optical Properties during the identification of gemstone. Specific gravity of Hibonite is 3.1 whereas that of Thulite is 3.1.
