Ajoite and Pyromorphite Chemical Formula
While comparing Ajoite and Pyromorphite 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 Ajoite and Pyromorphite chemical formula.
- Chemical formula of Ajoite- (K,Na)3Cu20Al3Si29O76(OH)16•~8(H2O)
- Chemical formula of Pyromorphite- Pb 5(PO 4) 3ClArthur Thomas , Gemstones (2009)
Ajoite and Pyromorphite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ajoite and Pyromorphite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ajoite and Pyromorphite Optical Properties during the identification of gemstone. Specific gravity of Ajoite is 6.5-7.1 whereas that of Pyromorphite is 6.5-7.1.
