Scorzalite and Alunite Physical Properties

Scorzalite and Alunite Chemical Formula

While comparing Scorzalite and Alunite 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 Scorzalite and Alunite chemical formula.

• Chemical formula of Scorzalite- (Fe2+ ,Mg)Al 2(PO 4) 2(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Alunite- KAl3(SO4)2(OH)6

Scorzalite and Alunite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Scorzalite and Alunite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Scorzalite and Alunite Optical Properties during the identification of gemstone. Specific gravity of Scorzalite is 2.6-2.9 whereas that of Alunite is 2.6-2.9.
