Beudantite and Astrophyllite Chemical Formula
While comparing Beudantite 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 Beudantite and Astrophyllite chemical formula.
- Chemical formula of Beudantite- PbFe+++3(AsO4)(SO4)(OH)6
- Chemical formula of Astrophyllite- (K,Na) 3(Fe2+ ,Mn) 7Ti 2Si 8O 24(O,OH) 7Anthony et al , Handbook of mineralogy (2001)
Beudantite and Astrophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Beudantite and Astrophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Beudantite and Astrophyllite Optical Properties during the identification of gemstone. Specific gravity of Beudantite is 3.2-3.4 whereas that of Astrophyllite is 3.2-3.4.
