Prehnite and Actinolite Chemical Formula
While comparing Prehnite and Actinolite 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 Prehnite and Actinolite chemical formula.
- Chemical formula of Prehnite- Ca2Al2Si3O12(OH)
- Chemical formula of Actinolite- Ca 2(Mg,Fe) 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
Prehnite and Actinolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Prehnite and Actinolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prehnite and Actinolite Optical Properties during the identification of gemstone. Specific gravity of Prehnite is 3.00 whereas that of Actinolite is 3.00.
