Sillimanite and Musgravite Physical Properties

Sillimanite and Musgravite Chemical Formula

While comparing Sillimanite and Musgravite 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 Sillimanite and Musgravite chemical formula.

• Chemical formula of Musgravite- (Mg,Fe,Zn)Al 6BeO 12Ulrich Henn and Claudio C.

Sillimanite and Musgravite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sillimanite and Musgravite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sillimanite and Musgravite Optical Properties during the identification of gemstone. Specific gravity of Sillimanite is 3.62-3.68 whereas that of Musgravite is 3.62-3.68.
