Malunga i-Cobalt
I-Cobalt iyinsimbi eqinile, ekhanyayo, emnyama-emnyama ne-blueish tinge. I-Cobalt compounds ikhiqiza umbala oluhlaza okwesibhakabhaka oqinile engilazini nasesitsheni. Iyingxenye ebalulekile ye-trace element njengengxenye ye-vitamin B12.
Izisebenziso
Amabhethri e-lithium-ion, ama-superalloys enjini ze-jet, ama-pigments aluhlaza okwesibhakabhaka, ama-alloys amagnetic, ne-vitamin B12.
Iqiniso elijabulisayo
I-cobalt ithola igama layo kusuka ku-'kobold' (isiJalimane se-goblin), ngoba abakhithi bamangalisa ama-goblins ngephunga elibulalayo lapho ama-ore e-cobalt ehlanganiswa khona.
