Application
- — Industrial chemistry (catalysis of chemical reactions);
- — permanent magnets: an alloy that contains up to 50% Co with chromium and vanadium, is used;
- — alloying with cobalt can improve the heat resistance of the alloy and improve the mechanical properties of steel, making it instrumental (drills, cutters, etc.);
- — magnetic properties of cobalt alloys allow to use them in equipment for magnetic recording, and in cores of transformers, electric motors;
- — silicide CoSi is an excellent thermoelectric material for thermoelectric generators with a high coefficient of efficiency;
- — radioactive 60 Co are used in medicine, gamma-ray flaw detection, and also for fueling nuclear boilers;
- — positive electrode in the manufacture of lithium batteries.
Storage
In closed warehouses or under a canopy, where adequate protection against mechanical and other damages is provided.
