Cobalt
Cobalt is most commonly used in metallic form.
Most of the cobalt consumed is used in the manufacture of superalloys.
These are metal formulations that are most commonly used in areas where
resistance to extreme conditions is required, e.g. B. in components of
jet engines or high-speed drills. Superalloys are also sometimes used in
biomedical implants such as hip replacements, although these implants
must be monitored for damage because metal nanoparticles generated by
wear can be easily absorbed and distributed throughout the body. Cobalt
in cobalamin, also known as vitamin B12, is an essential nutrient, but
excess free cobalt ions in the body have toxic effects.
Cobalt is also used in other alloy applications. It is found in both
alnico and samarium cobalt magnets, both of which are widely used in the
industry. Cobalt is also found in combination with primary electrode
metals in lithium-ion, nickel-cadmium, and nickel-metal hydride
batteries. Because of its attractive appearance, extreme hardness and
resistance to oxidation, cobalt can be used as a metal to clad other
materials, either alone or as a base for other coatings such as
porcelain enamels. Platinum used in jewelry making contains five percent
cobalt as this makes an alloy suitable for highly detailed casting.
There are two other main uses of cobalt in industry. The first acts as a
catalyst: cobalt compounds are used industrially to produce polymer
precursors to remove sulfur-containing impurities from petroleum and to
improve the adhesion of steel to rubber for the manufacture of steel
belted tires. In addition, cobalt catalysts are added as drying agents
for paints and varnishes and are used in a variety of other chemical
processes, both on an industrial and laboratory scale. The second main
application is as a binder in cemented carbides, where extremely hard
materials are used in machining metals such as steel.
Finally, cobalt radioisotopes perform some notable functions. Cobalt-60
is a radioactive isotope that is used to generate gamma rays for the
sterilization of food and medical supplies and for use in both medical
radiation therapy and the production of industrial X-ray images.
Cobalt-57 is used as a tracer in medical imaging, primarily to monitor
vitamin B12 uptake.
The most important cobalt ores are cobaltite, erythritol, glaucodot and
skutterudite, all of which are commercially exploited. However, a
significant portion of the metal is also obtained through processing
by-products of copper and nickel mining. Cobalt catalysts and cobalt
alloy waste can also be recycled to produce high purity cobalt.
