Chitsulo chosunthikachi chaphatikiza malo ake m'malo achikhalidwe, monga ma superalloys, ndipo chagwiritsidwa ntchito kwambiri pazinthu zina zatsopano, monga mabatire omwe amatha kuchangidwa.
Aloyi -
Ma superalloys opangidwa ndi cobalt amadya kwambiri cobalt yomwe imapangidwa. Kukhazikika kwa kutentha kwa ma aloyiwa kumawapangitsa kukhala oyenera kugwiritsidwa ntchito pamasamba a turbine pama turbines a gasi ndi injini zandege za jet, ngakhale ma aloyi a nickel a single crystal alloys amawaposa pankhaniyi. Ma alloys opangidwa ndi cobalt nawonso amakhala ndi dzimbiri komanso osavala. Ma aloyi apadera a cobalt-chromium-molybdenum amagwiritsidwa ntchito pazinthu zopangira ma prosthetic monga m'malo mwa chiuno ndi mawondo. Ma aloyi a cobalt amagwiritsidwanso ntchito popanga mano, komwe amakhala othandiza kupewa ziwengo ku nickel. Zitsulo zina zothamanga kwambiri zimagwiritsanso ntchito cobalt kuti ziwonjezere kutentha komanso kusagwira ntchito. Ma alloys apadera a aluminiyamu, faifi tambala, cobalt ndi chitsulo, omwe amadziwika kuti Alnico, ndi a samarium ndi cobalt (samarium-cobalt maginito) amagwiritsidwa ntchito mu maginito osatha.
Mabatire-
Lithium cobalt okusayidi (LiCoO2) amagwiritsidwa ntchito kwambiri mu Lithium ion batire maelekitirodi. Mabatire a nickel-cadmium (NiCd) ndi nickel metal hydride (NiMH) alinso ndi kuchuluka kwa cobalt.
Chothandizira-
Mankhwala angapo a cobalt amagwiritsidwa ntchito popanga mankhwala monga chothandizira. Cobalt acetate imagwiritsidwa ntchito popanga terephthalic acid komanso dimethyl terephthalic acid, zomwe ndizofunikira kwambiri popanga Polyethylene terephthalate. Kusintha kwa nthunzi ndi hydrodesulfuration popanga mafuta a petroleum, omwe amagwiritsa ntchito ma cobalt molybdenum aluminium oxides ngati chothandizira, ndi ntchito ina yofunika. Cobalt ndi mankhwala ake, makamaka cobalt carboxylates (otchedwa cobalt sopo), ndi zabwino okosijeni catalysts. Amagwiritsidwa ntchito popanga utoto, ma vanishi, ndi inki ngati zowumitsa pogwiritsa ntchito ma oxidation azinthu zina. Ma carboxylates omwewo amagwiritsidwa ntchito kupititsa patsogolo kumamatira kwachitsulo ku mphira m'matayala achitsulo okhala ndi lamba.
Pigments ndi mitundu -
Zaka za m'ma 19 zisanafike, kugwiritsidwa ntchito kwakukulu kwa cobalt kunali ngati pigment. Kuyambira m'zaka zapakati kupanga smalt, galasi lamtundu wa buluu linkadziwika. Smalt imapangidwa ndi kusungunula kusakaniza kwa mchere wokazinga wa smaltite, quartz ndi potaziyamu carbonate, kutulutsa galasi lakuda la silicate lakuda lomwe limaphwanyidwa pambuyo pa kupanga. Smalt ankagwiritsidwa ntchito kwambiri popanga magalasi komanso mtundu wa pigment pojambula. Mu 1780 Sven Rinman anapeza cobalt wobiriwira ndipo mu 1802 Louis Jacques Thénard anapeza cobalt blue. Mitundu iwiri ya cobalt buluu, cobalt aluminate, ndi cobalt wobiriwira, osakaniza a cobalt (II) okusayidi ndi zinc oxide, ankagwiritsidwa ntchito ngati inki pojambula chifukwa cha kukhazikika kwawo kwapamwamba. Cobalt wakhala akugwiritsidwa ntchito kupaka galasi kuyambira Bronze Age.
Kufotokozera
Chitsulo cholimba, cholimba, chofanana ndi chitsulo ndi faifi tambala m'mawonekedwe, cobalt imakhala ndi mphamvu ya maginito pafupifupi magawo awiri mwa atatu a chitsulo. Nthawi zambiri amapezeka ngati chitsulo cha nickel, siliva, lead, copper, ndi iron ores ndipo amapezeka mu meteorites.
Cobalt nthawi zambiri amaphatikizidwa ndi zitsulo zina chifukwa cha mphamvu yake yachilendo ya maginito ndipo amagwiritsidwa ntchito pa electroplating chifukwa cha maonekedwe ake, kuuma kwake komanso kukana kutsekemera kwa okosijeni.
