Chlorapatite and Hibschite Physical Properties

Chlorapatite and Hibschite Chemical Formula

While comparing Chlorapatite and Hibschite 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 Chlorapatite and Hibschite chemical formula.

• Chemical formula of Chlorapatite- Ca 5(PO 4) 3ClAnthony et al , Handbook of mineralogy (2001)
• Chemical formula of Hibschite- Ca 3Al 2(SiO 4) 3-x(OH) 4x (x=0.2 to 1.5)Anthony et al , Handbook of mineralogy (2001)

Chlorapatite and Hibschite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chlorapatite and Hibschite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chlorapatite and Hibschite Optical Properties during the identification of gemstone. Specific gravity of Chlorapatite is 3.05-3.08 whereas that of Hibschite is 3.05-3.08.
