Sapphire and Brucite Physical Properties

Sapphire and Brucite Chemical Formula

While comparing Sapphire 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 Sapphire and Brucite chemical formula.

• Chemical formula of Sapphire- Al ₂ O ₃
• Chemical formula of Brucite- Mg(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)

Sapphire and Brucite Specific Gravity

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