Though the amount of research on cobalt oxide nanoparticles is still relatively new, researchers have found that these particles have great potential for us in chemical and industrial areas. ==Characteristics== Cobalt oxide nanoparticles appear white in color and are magnetic p-type semiconductors. It is interesting to note that the particles will convert into cobalt metal upon heating at 900 °C. Even though cobalt oxide nanoparticles have many beneficial uses, the substance is still toxic to humans and also aquatic life. It is harmful when swallowed and also acts as a skin irritant.
