Atacamite and Apatite Chemical Formula
While comparing Atacamite and Apatite 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 Atacamite and Apatite chemical formula.
- Chemical formula of Atacamite- Cu2Cl(OH)3
- Chemical formula of Apatite- Ca 5(PO 4) 3(F,OH,Cl)Walter Schumann , Gemstones of the world (2001) More from other references
Atacamite and Apatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Atacamite and Apatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Atacamite and Apatite Optical Properties during the identification of gemstone. Specific gravity of Atacamite is 3.16-3.23 whereas that of Apatite is 3.16-3.23.
