Le nsimbi enemisebenzi eminingi iye yahlanganisa indawo yayo ezindaweni zendabuko, njengama-superalloy, futhi ithole ukusetshenziswa okukhulu kwezinye izinhlelo zokusebenza ezintsha, njengakumabhethri aphinde ashajwa.
Ama-alloys-
I-cobalt-based superalloys idla iningi le-cobalt ekhiqizwayo. Ukuzinza kwezinga lokushisa kwalawa ma-alloys kuwenza afanelekele ukusetshenziswa kuma-turbine blades wezinjini zegesi nezinjini zendiza yendiza, nakuba ama-crystal alloys enziwe nge-nickel eyodwa edlula kuwo kulokhu. Ama-alloys asekelwe ku-cobalt nawo ayagqwala futhi awagugi. Ama-alloys akhethekile e-cobalt-chromium-molybdenum asetshenziselwa izingxenye zokufakelwa ezifana nokushintshwa kwe-hip namadolo. Ama-alloys e-cobalt nawo asetshenziselwa i-prosthetics yamazinyo, lapho ewusizo ukugwema ukungezwani ne-nickel. Ezinye izinsimbi zejubane eliphezulu zisebenzisa i-cobalt ukukhulisa ukushisa nokumelana nokugqoka. Ama-alloys akhethekile e-aluminium, i-nickel, i-cobalt ne-iron, eyaziwa ngokuthi i-Alnico, kanye ne-samarium ne-cobalt (umazibuthe we-samarium-cobalt) asetshenziswa kozibuthe abangapheli.
Amabhethri-
I-Lithium cobalt oxide (LiCoO2) isetshenziswa kabanzi kuma-electrode ebhethri e-Lithium ion. Amabhethri e-nickel-cadmium (NiCd) kanye ne-nickel metal hydride (NiMH) nawo aqukethe amanani abalulekile e-cobalt.
I-Catalyst-
Amakhompiyutha amaningana e-cobalt asetshenziswa ekuphenduleni kwamakhemikhali njengama-catalysts. I-cobalt acetate isetshenziselwa ukukhiqizwa kwe-terephthalic acid kanye ne-dimethyl terephthalic acid, okuyizinhlanganisela ezibalulekile ekukhiqizeni i-Polyethylene terephthalate. I-steam reforming kanye ne-hydrodesulfuration ekukhiqizeni i-petroleum, esebenzisa i-cobalt molybdenum aluminium oxides exutshwe njenge-catalyst, ingenye isicelo esibalulekile. I-Cobalt nezinhlanganisela zayo, ikakhulukazi i-cobalt carboxylates (eyaziwa ngokuthi izinsipho ze-cobalt), ziyizisusa ezinhle ze-oxidation. Asetshenziswa kumapende, amavanisha, noyinki njengezinto ezomisayo ngokusebenzisa i-oxidation yezinhlanganisela ezithile. Ama-carboxylate afanayo asetshenziselwa ukwenza ngcono ukunamathela kwensimbi enjolweni kumathayi e-radial anebhande lensimbi.
Izingulube nemibala-
Ngaphambi kwekhulu le-19, ukusetshenziswa kakhulu kwe-cobalt kwakuyi-pigment. Kusukela ku-midage ukukhiqizwa kwe-smalt, ingilazi enombala ohlaza okwesibhakabhaka kwayaziwa. I-Smalt ikhiqizwa ngokuncibilikisa ingxube ye-mineral smaltite ethosiwe, i-quartz ne-potassium carbonate, ikhiqiza ingilazi ye-silicate eluhlaza okwesibhakabhaka emnyama egaywe ngemva kokukhiqizwa. I-Smalt yayisetshenziswa kakhulu ukwenza umbala wengilazi nanjenge-pigment yemidwebo. Ngo-1780 uSven Rinman wathola i-cobalt eluhlaza futhi ngo-1802 uLouis Jacques Thénard wathola i-cobalt eluhlaza okwesibhakabhaka. Imibala emibili i-cobalt eluhlaza okwesibhakabhaka, i-cobalt aluminate, kanye ne-cobalt eluhlaza, ingxube ye-cobalt(II) oxide ne-zinc oxide, yasetshenziswa njengezingulube zemidwebo ngenxa yokuqina kwayo okuphezulu. I-Cobalt isetshenziselwe ukufaka umbala ingilazi kusukela ngeNkathi Yebhulonzi.
Incazelo
I-brittle, insimbi eqinile, efana nensimbi ne-nickel ngokubukeka, i-cobalt inokufinyeleleka kazibuthe cishe okubili kokuthathu kwensimbi. Ivame ukutholwa njengomkhiqizo we-nickel, isiliva, umthofu, ithusi, nensimbi futhi ikhona kuma-meteorites.
I-Cobalt ivame ukuhlanganiswa nezinye izinsimbi ngenxa yamandla ayo kazibuthe angavamile futhi isetshenziselwa i-electroplating ngenxa yokubukeka kwayo, ubulukhuni kanye nokumelana ne-oxidation.
