Whitlockite and Wernerite Physical Properties

Whitlockite and Wernerite Chemical Formula

While comparing Whitlockite and Wernerite 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 Wernerite 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 Wernerite- Na 4(Al,Si) 12O 24Cl to Ca 4(Si,Al) 12O 24(CO 3,SO 4)Arthur Thomas , Gemstones (2009)

Whitlockite and Wernerite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Whitlockite and Wernerite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Whitlockite and Wernerite Optical Properties during the identification of gemstone. Specific gravity of Whitlockite is 2.50-2.80 whereas that of Wernerite is 2.50-2.80.
