Brucite and Norbergite Physical Properties

Brucite and Norbergite Chemical Formula

While comparing Brucite and Norbergite 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 Brucite and Norbergite chemical formula.

• Chemical formula of Norbergite- Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001)

Brucite and Norbergite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Brucite and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brucite and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Brucite is 3.177 whereas that of Norbergite is 3.177.
