Halite and Cordierite Chemical Formula
While comparing Halite and Cordierite 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 Halite and Cordierite chemical formula.
- Chemical formula of Halite- NaCl
- Chemical formula of Cordierite- Mg2Al4Si5O18
Halite and Cordierite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Halite and Cordierite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Halite and Cordierite Optical Properties during the identification of gemstone. Specific gravity of Halite is 2.57-2.66 whereas that of Cordierite is 2.57-2.66.
