Cobalt is often alloyed with iron, nickel and other metals to make Alnico, an alloy 

of unusual magnetic strength with many important uses. Samarium-cobalt, for 

instance, is one of the highest strength magnet alloys known. Cobalt compounds 

are used to produce a brilliant and permanent blue color in ceramic glazes, glass,  

High Purity (99.999%) Cobalt Oxide (Co3O4) Powderpottery, tiles, and enamels. 

Co-60, a commercially important radioisotope, is useful as a radioactive tracer 

and gamma ray source. High Purity (99.999%) Cobalt (Co) Sputtering 

TargetCobalt is available as metal and compounds with purities from 99% to 

99.999% (ACS grade to ultra-high purity). Elemental or metallic forms include 

pellets, rod, wire and granules for evaporation source material purposes. Cobalt 

nanoparticles and nanopowders are also available. Cobalt oxides are available 

in powder and dense pellet form for such uses as optical coating and thin film 

applications. Oxides tend to be insoluble. Cobalt fluorides are another insoluble 

form for uses in which oxygen is undesirable such as metallurgy, chemical and 

physical vapor deposition and in some optical coatings. Cobalt is also available in 

soluble forms including chlorides, nitrates and acetates. These compounds can be 

manufactured as solutions at specified stoichiometries.
