Eudialyte and Thulite Chemical Formula

While comparing Eudialyte and Thulite 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 Eudialyte and Thulite chemical formula.

  • Chemical formula of Eudialyte- Na 4(Ca,Ce) 2(Fe,Mn,Y)ZrSi 8O 22(OH,Cl) 2Ulrich Henn and Claudio C.
  • Chemical formula of Thulite- Ca2Al3(SiO4)3(OH)

Eudialyte and Thulite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Eudialyte and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Eudialyte and Thulite Optical Properties during the identification of gemstone. Specific gravity of Eudialyte is 3.1 whereas that of Thulite is 3.1.
