Hauyne and Esperite Chemical Formula
While comparing Hauyne and Esperite 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 Hauyne and Esperite chemical formula.
- Chemical formula of Hauyne- (Na,Ca)4-8Al6Si6(O,S)24(SO4,Cl)1-2
- Chemical formula of Esperite- PbCa 3Zn 4(SiO 4) 4Anthony et al , Handbook of mineralogy (2001)
Hauyne and Esperite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hauyne and Esperite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hauyne and Esperite Optical Properties during the identification of gemstone. Specific gravity of Hauyne is 4.28-4.42 whereas that of Esperite is 4.28-4.42.
