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

Pyrophyllite and Stibiotantalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pyrophyllite and Stibiotantalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrophyllite and Stibiotantalite Optical Properties during the identification of gemstone. Specific gravity of Pyrophyllite is Not Available whereas that of Stibiotantalite is Not Available.
