Hibschite and Agrellite Physical Properties

Hibschite and Agrellite Chemical Formula

While comparing Hibschite and Agrellite 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 Agrellite 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 Agrellite- NaCa2Si4O10F

Hibschite and Agrellite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hibschite and Agrellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hibschite and Agrellite Optical Properties during the identification of gemstone. Specific gravity of Hibschite is 2.88 whereas that of Agrellite is 2.88.
