Cobalt is a hard, silvery white, shiny, brittle ferromagnetic element. Is a member of the eighth group of the periodic table. This element is chemically active and forms many compounds. Cobalt is stable in air and is not affected by water, but is slowly attacked by dilute acids.
The process of processing cobalt from catalytic wastes is such that during a scientific process, from the wastes to chemical compounds with very high purity. High-performance chemical compounds are vitally used in industries such as paints, pigments, catalysts, the automotive and plating industries.
Application
- In many alloys (superalloys for gas turbine engine parts, corrosion resistant alloys, high speed steels, cement carbides)
- In magnets and magnetic recording media
- As a catalyst for the petroleum and chemical industries
- As drying agents for paints
- Cobalt blue ink
- In Chinese industries, pottery, stained glass, tiles and enamel jewelry
- Use of radioactive isotopes (cobalt-60) in medical treatment and irradiation to preserve food and protect the consumer
