Iddingsite and Fluorapatite Physical Properties

Iddingsite and Fluorapatite Chemical Formula

While comparing Iddingsite and Fluorapatite 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 Iddingsite and Fluorapatite chemical formula.

• Chemical formula of Iddingsite- MgO.Fe2O3.3SiO2•4(H2O)
• Chemical formula of Fluorapatite- Ca 5(PO 4) 3FAnthony et al , Handbook of mineralogy (2001)

Iddingsite and Fluorapatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Iddingsite and Fluorapatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Iddingsite and Fluorapatite Optical Properties during the identification of gemstone. Specific gravity of Iddingsite is 3.1-3.25 whereas that of Fluorapatite is 3.1-3.25.
