Pectolite and Foitite Physical Properties

Pectolite and Foitite Chemical Formula

While comparing Pectolite and Foitite 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 Pectolite and Foitite chemical formula.

• Chemical formula of Pectolite- Ca 2NaHSi 3O 9Ulrich Henn and Claudio C.
• 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)

Pectolite and Foitite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pectolite and Foitite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pectolite and Foitite Optical Properties during the identification of gemstone. Specific gravity of Pectolite is 3.17 whereas that of Foitite is 3.17.
