Clinochlore and Alunite Physical Properties

Clinochlore and Alunite Chemical Formula

While comparing Clinochlore 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 Clinochlore and Alunite chemical formula.

• Chemical formula of Clinochlore- (Mg,Fe2+ ) 5Al(Si 3Al)O 10(OH) 8Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Alunite- KAl3(SO4)2(OH)6

Clinochlore and Alunite Specific Gravity

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