The use of cobalt
Industrial chemistry (catalysis of chemical reactions), alloying heat-resistant alloys. Electrical engineering: cobalt lithium — a highly effective positive electrode in lithium batteries. The magnetic properties allow the use of cobalt in the apparatus for magnetic recording, and in the cores of transformers, electric motors. A silicide is an excellent thermoelectric material for power generators with high efficiency. Radioactive 60 co used in medicine, gamma radiography, and also for fueling nuclear boilers;
