Xonotlite and Apatite Chemical Formula

While comparing Xonotlite and Apatite 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 Xonotlite and Apatite chemical formula.

Xonotlite and Apatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Xonotlite and Apatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Xonotlite and Apatite Optical Properties during the identification of gemstone. Specific gravity of Xonotlite is 3.16-3.23 whereas that of Apatite is 3.16-3.23.
