Friedelite and Sunstone Chemical Formula
While comparing Friedelite and Sunstone 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 Friedelite and Sunstone chemical formula.
- Chemical formula of Friedelite- Mn 8Si 6O 15(OH,Cl) 10Ulrich Henn and Claudio C.
- Chemical formula of Sunstone- Microcline: KAlSi3O8 Oligoclase: (Na,Ca)Al1-2Si3-2O8
Friedelite and Sunstone Specific Gravity
Another important criteria for qualitative analysis of gemstones is Friedelite and Sunstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Friedelite and Sunstone Optical Properties during the identification of gemstone. Specific gravity of Friedelite is 2.62-2.65 whereas that of Sunstone is 2.62-2.65.
