Tremolite and Calcite Chemical Formula
While comparing Tremolite and Calcite 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 Tremolite and Calcite chemical formula.
- Chemical formula of Tremolite- Ca 2Mg 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
- Chemical formula of Calcite- CaCO 3Ulrich Henn and Claudio C.
Tremolite and Calcite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tremolite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tremolite and Calcite Optical Properties during the identification of gemstone. Specific gravity of Tremolite is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
