Moroxite and Sillimanite Physical Properties

Moroxite and Sillimanite Chemical Formula

While comparing Moroxite and Sillimanite 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 Moroxite and Sillimanite chemical formula.

• Chemical formula of Moroxite- Ca 5(F,Cl)(PO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Sillimanite- Al 2SiO 5Michael O’Donoghue , Gems, Sixth Edition (2006)

Moroxite and Sillimanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moroxite and Sillimanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moroxite and Sillimanite Optical Properties during the identification of gemstone. Specific gravity of Moroxite is 3.20-3.26 whereas that of Sillimanite is 3.20-3.26.
