Cryolite and Pumpellyite Chemical Formula

While comparing Cryolite and Pumpellyite 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 Cryolite and Pumpellyite chemical formula.

  • Chemical formula of Cryolite- Na 3AlF 6Ulrich Henn and Claudio C.
  • Chemical formula of Pumpellyite- Ca 2(Mg,Fe,Mn,Al) 2(SiO 4)(Si 2O 7)(OH) 2 · H 2OUlrich Henn and Claudio C.

Cryolite and Pumpellyite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Pumpellyite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Pumpellyite Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 3.20-3.30 whereas that of Pumpellyite is 3.20-3.30.
