Friedelite and Williamsite Physical Properties

Friedelite and Williamsite Chemical Formula

While comparing Friedelite and Williamsite 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 Friedelite and Williamsite chemical formula.

• Chemical formula of Friedelite- Mn 8Si 6O 15(OH,Cl) 10Ulrich Henn and Claudio C.
• Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)

Friedelite and Williamsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Friedelite and Williamsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Friedelite and Williamsite Optical Properties during the identification of gemstone. Specific gravity of Friedelite is 2.51-2.63 whereas that of Williamsite is 2.51-2.63.
