Zircon and Hibschite Chemical Formula
While comparing Zircon and Hibschite 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 Zircon and Hibschite chemical formula.
- Chemical formula of Zircon- ZrSiO4
- Chemical formula of Hibschite- Ca 3Al 2(SiO 4) 3-x(OH) 4x (x=0.2 to 1.5)Anthony et al , Handbook of mineralogy (2001)
Zircon and Hibschite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zircon and Hibschite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zircon and Hibschite Optical Properties during the identification of gemstone. Specific gravity of Zircon is 3.05-3.08 whereas that of Hibschite is 3.05-3.08.
