Malachite and Foitite Chemical Formula
While comparing Malachite and Foitite 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 Malachite and Foitite chemical formula.
- Chemical formula of Malachite- Cu2CO3(OH)2
- Chemical formula of Foitite- Na x[Fe2+2(Al,Fe3+ )]Al 6(BO 3) 3Si 6O 18(OH) 4Anthony et al , Handbook of mineralogy (2001)
Malachite and Foitite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Malachite and Foitite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Malachite and Foitite Optical Properties during the identification of gemstone. Specific gravity of Malachite is 3.17 whereas that of Foitite is 3.17.
