Apophyllite and Actinolite Chemical Formula
While comparing Apophyllite 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 Apophyllite and Actinolite chemical formula.
- Chemical formula of Apophyllite- KCa 4Si 8O 20(F,OH) · 8H 2OUlrich Henn and Claudio C.
- Chemical formula of Actinolite- Ca 2(Mg,Fe) 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
Apophyllite and Actinolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apophyllite and Actinolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apophyllite and Actinolite Optical Properties during the identification of gemstone. Specific gravity of Apophyllite is 3.00 whereas that of Actinolite is 3.00.
