Diopside and Astrophyllite Chemical Formula
While comparing Diopside and Astrophyllite 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 Diopside and Astrophyllite chemical formula.
- Chemical formula of Diopside- CaMgSi2O6
- Chemical formula of Astrophyllite- (K,Na) 3(Fe2+ ,Mn) 7Ti 2Si 8O 24(O,OH) 7Anthony et al , Handbook of mineralogy (2001)
Diopside and Astrophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Diopside and Astrophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diopside and Astrophyllite Optical Properties during the identification of gemstone. Specific gravity of Diopside is 3.2-3.4 whereas that of Astrophyllite is 3.2-3.4.
