Tanzanite and Stibiotantalite Chemical Formula
While comparing Tanzanite and Stibiotantalite 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 Tanzanite and Stibiotantalite chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Stibiotantalite- SbTaO 4Ulrich Henn and Claudio C.
Tanzanite and Stibiotantalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Stibiotantalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Stibiotantalite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is Not Available whereas that of Stibiotantalite is Not Available.
