Periclase and Tantalite Chemical Formula
While comparing Periclase and Tantalite 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 Periclase and Tantalite chemical formula.

Periclase and Tantalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Periclase and Tantalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Periclase and Tantalite Optical Properties during the identification of gemstone. Specific gravity of Periclase is 5.2 whereas that of Tantalite is 5.2.
