Gyrolite and Pyrophyllite Chemical Formula
While comparing Gyrolite and Pyrophyllite 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 Gyrolite and Pyrophyllite chemical formula.
- Chemical formula of Gyrolite- NaCa16Si23AlO60(OH)8•64(H2O)
- Chemical formula of Pyrophyllite- Al 2Si 4O 10(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Gyrolite and Pyrophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gyrolite and Pyrophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gyrolite and Pyrophyllite Optical Properties during the identification of gemstone. Specific gravity of Gyrolite is 2.65-2.90 whereas that of Pyrophyllite is 2.65-2.90.
