Stibiotantalite and Xonotlite Chemical Formula
While comparing Stibiotantalite and Xonotlite 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 Stibiotantalite and Xonotlite chemical formula.

Stibiotantalite and Xonotlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Stibiotantalite and Xonotlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stibiotantalite and Xonotlite Optical Properties during the identification of gemstone. Specific gravity of Stibiotantalite is 2.71-2.72 whereas that of Xonotlite is 2.71-2.72.
