Fluorite and Eudialyte Chemical Formula
While comparing Fluorite and Eudialyte 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 Fluorite and Eudialyte chemical formula.
- Chemical formula of Fluorite- CaF2
- Chemical formula of Eudialyte- Na 4(Ca,Ce) 2(Fe,Mn,Y)ZrSi 8O 22(OH,Cl) 2Ulrich Henn and Claudio C.
Fluorite and Eudialyte Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fluorite and Eudialyte Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluorite and Eudialyte Optical Properties during the identification of gemstone. Specific gravity of Fluorite is 2.74-3.00 whereas that of Eudialyte is 2.74-3.00.
