Apatite and Sonolite Physical Properties

Apatite and Sonolite Chemical Formula

While comparing Apatite and Sonolite 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 Apatite and Sonolite chemical formula.

• Chemical formula of Sonolite- Mn2+9(SiO 4) 4(OH,F) 2Anthony et al , Handbook of mineralogy (2001)

Apatite and Sonolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Apatite and Sonolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apatite and Sonolite Optical Properties during the identification of gemstone. Specific gravity of Apatite is 3.82-4.00 whereas that of Sonolite is 3.82-4.00.
