Fluorapatite and Wernerite Physical Properties

Fluorapatite and Wernerite Chemical Formula

While comparing Fluorapatite 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 Fluorapatite and Wernerite chemical formula.

• Chemical formula of Fluorapatite- Ca 5(PO 4) 3FAnthony 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)

Fluorapatite and Wernerite Specific Gravity

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