Foitite and Calcite Physical Properties

Foitite and Calcite Chemical Formula

While comparing Foitite 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 Foitite and Calcite chemical formula.

• Chemical formula of Foitite- Na x[Fe2+2(Al,Fe3+ )]Al 6(BO 3) 3Si 6O 18(OH) 4Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Calcite- CaCO 3Ulrich Henn and Claudio C.

Foitite and Calcite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Foitite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Foitite and Calcite Optical Properties during the identification of gemstone. Specific gravity of Foitite is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
