Hibschite and Mottramite Physical Properties

Hibschite and Mottramite Chemical Formula

While comparing Hibschite and Mottramite 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 Hibschite and Mottramite chemical formula.

• 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)
• Chemical formula of Mottramite- PbCu(VO4)(OH)

Hibschite and Mottramite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hibschite and Mottramite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hibschite and Mottramite Optical Properties during the identification of gemstone. Specific gravity of Hibschite is 5.9 whereas that of Mottramite is 5.9.
