Sapphire and Pyroxmangite Chemical Formula
While comparing Sapphire and Pyroxmangite 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 Sapphire and Pyroxmangite chemical formula.
- Chemical formula of Sapphire- Al 2 O 3
- Chemical formula of Pyroxmangite- (Fe,Mn) 7Si 7O 21Ulrich Henn and Claudio C.
Sapphire and Pyroxmangite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sapphire and Pyroxmangite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Pyroxmangite Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 3.76-3.77 whereas that of Pyroxmangite is 3.76-3.77.
