Whitlockite and Spinel Physical Properties

Whitlockite and Spinel Chemical Formula

While comparing Whitlockite and Spinel 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 Whitlockite and Spinel chemical formula.

• Chemical formula of Whitlockite- Ca 9(Mg,Fe2+ )(PO 4) 6(PO 3OH)Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Spinel- MgAl₂O₄

Whitlockite and Spinel Specific Gravity

Another important criteria for qualitative analysis of gemstones is Whitlockite and Spinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Whitlockite and Spinel Optical Properties during the identification of gemstone. Specific gravity of Whitlockite is 3.64-3.66 whereas that of Spinel is 3.64-3.66.
