Iddingsite and Ajoite Chemical Formula
While comparing Iddingsite and Ajoite 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 Iddingsite and Ajoite chemical formula.
- Chemical formula of Iddingsite- MgO.Fe2O3.3SiO2•4(H2O)
- Chemical formula of Ajoite- (K,Na)3Cu20Al3Si29O76(OH)16•~8(H2O)
Iddingsite and Ajoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Iddingsite and Ajoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Iddingsite and Ajoite Optical Properties during the identification of gemstone. Specific gravity of Iddingsite is 2.96 whereas that of Ajoite is 2.96.
