Cobalt Oxide (Co3O4) nanoparticles

The potential for nanoparticles to be used in biological, chemical, and industrial areas is infinite. Researchers are working on new applications constantly.

Cobalt oxide nanoparticles appear as a white powder with spinel crystal structure. They are an important magnetic material, and are P-type semiconductors. When nano-cobalt oxide is exposed to the hydrogen flame and heated to 900°C (1652°F), it changes into metal cobalt.

Cobalt oxide nanoparticles are graded as harmful to humans and dangerous for the environment. They can be harmful if swallowed, and cause allergic skin reactions. They are also very toxic to aquatic life with long lasting effects.

Applications:

The key applications of cobalt oxide nanoparticles are as follows:
