Adamite and Periclase Chemical Formula

While comparing Adamite and Periclase 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 Adamite and Periclase chemical formula.

  • Chemical formula of Adamite- Zn 2(AsO 4)(OH)Michael O’Donoghue , Gems, Sixth edition (2006)
  • Chemical formula of Periclase- MgOMichael O’Donoghue , Gems, Sixth Edition (2006)

Adamite and Periclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Adamite and Periclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Adamite and Periclase Optical Properties during the identification of gemstone. Specific gravity of Adamite is 3.7-3.9 whereas that of Periclase is 3.7-3.9.
