Inderite and Alunite Physical Properties

Inderite and Alunite Chemical Formula

While comparing Inderite 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 Inderite and Alunite chemical formula.

• Chemical formula of Inderite- MgB 3O 3(OH) 5 · 5H 2OMichael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Alunite- KAl3(SO4)2(OH)6

Inderite and Alunite Specific Gravity

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