Chemical Structure Depiction

The chemical Structure of Cobalt Oxide:

Cobalt oxide is a mineral compound with the molecular formula of CoO and the structure of this compound is in the form of a typical spinel structure. Each cubic unit cell contains four Co²⁺ and four O²⁻ ions.

Cobalt Oxide Soluble or Insoluble:

Cobalt oxide crystals are insoluble or partially soluble in water but are highly soluble in acids and alkaline solutions. It is also insoluble in ammonium hydroxide and soluble in acidic and alkaline hydroxides.

Production of Cobalt Oxide:

• This substance is usually obtained by heating cobalt hydroxide precipitated from sodium hypochlorite solution. The reaction equation is shown in the figure below:

        Co (OH) ₂ → CoO + H₂O

• Other ways of producing this material include controlled oxidation of cobalt metal at temperatures above 900 ° C and cooling it at room temperature and controlled. This powder composition is prepared for the thermal decomposition of cobalt nitrate or sodium carbonate.

        2Co₃O₆ → 6CoO + O₂

• Production of coal raw materials.
• As a color in glass and ceramics. like chrome oxide 

• Use in hard alloys.
• As a pigment.
• animals feed and fertilizer.
• production of cobalt (II) salts.
• In temperature and gas sensors.

Cobalt Oxide in Medicine:

Cobalt oxide although it has a wide range of applications in the production of superconductors, semiconductors, sensors, MRI, and biomedicine, it’s a nanoscale biological synthesis with a completely green method for the production of cobalt oxide nanoparticles is a major achievement in the medical sciences. The nanoparticles of this material show different antibacterial potentials against different types of pathogenic bacteria. These compounds are more compatible with red blood cells than macrophages and have antioxidant, regenerative, and enzyme inhibitory properties.

Cobalt Oxide Nanoparticles:

Recently, special attention has been paid to preparing Co₃O₄ with nanostructure and improving its properties, so that separate nanostructures such as films, tubes, fibers, and rods have been made from this material. Cobalt oxide is often used for catalytic and magnetic applications. One of the important applications of cobalt oxide nanoparticles:

• In medicine, especially for drug delivery and magnetic resonance imaging (MRI).
• Biological sensors.
