Sphene and Brucite Physical Properties

Sphene and Brucite Chemical Formula

While comparing Sphene and Brucite 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 Sphene and Brucite chemical formula.

Sphene and Brucite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sphene and Brucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sphene and Brucite Optical Properties during the identification of gemstone. Specific gravity of Sphene is 2.39 whereas that of Brucite is 2.39.
