Creedite and Actinolite Chemical Formula
While comparing Creedite 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 Creedite and Actinolite chemical formula.
- Chemical formula of Creedite- Ca 3Al 2(SO 4)(F,OH) 10Ulrich Henn and Claudio C.
- Chemical formula of Actinolite- Ca 2(Mg,Fe) 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
Creedite and Actinolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Creedite and Actinolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Creedite and Actinolite Optical Properties during the identification of gemstone. Specific gravity of Creedite is 3.00 whereas that of Actinolite is 3.00.
