Iyi simbi inoshanda zvakasiyana-siyana yakabatanidza chinzvimbo chayo munzvimbo dzechinyakare, senge superalloys, uye yakawana kushandiswa kukuru mune mamwe maapplication matsva, senge mumabhatiri anochajwa.
Alloys-
Cobalt-based superalloys inoshandisa yakawanda yecobalt inogadzirwa. Kugadzikana kwetembiricha yearoyi aya kunoita kuti akwanise kushandiswa mumaturbine blades emagetsi emagetsi uye injini dzendege dzejeti, kunyangwe nickel-based single crystal alloys inovapfuura panyaya iyi. Cobalt-based alloys zvakare inoora uye inodzivirira kupfeka. Special cobalt-chromium-molybdenum alloys inoshandiswa kune nhengo dzeprosthetic dzakadai sehudyu nemabvi kutsiva. Cobalt alloys anoshandiswawo kune mazino prosthetics, uko anobatsira kudzivirira allergies kune nickel. Mamwe masimbi ekumhanya anoshandisawo cobalt kuwedzera kupisa uye kupfeka-kusagadzikana. Iwo akakosha alloys ealuminium, nickel, cobalt nesimbi, inozivikanwa seAlnico, uye yesamarium uye cobalt (samarium-cobalt magineti) anoshandiswa mumagineti echigarire.
Mabhatiri-
Lithium cobalt oxide (LiCoO2) inoshandiswa zvakanyanya muLithium ion bhatiri electrodes. Nickel-cadmium (NiCd) uye nickel metal hydride (NiMH) mabhatiri anewo huwandu hwakakosha hwecobalt.
Catalyst-
Makomisheni akati wandei ecobalt anoshandiswa mukuchinja kwemakemikari senge zvinokonzeresa. Cobalt acetate inoshandiswa pakugadzirwa kwe terephthalic acid pamwe ne dimethyl terephthalic acid, iyo inonyanya kukosha mukugadzirwa kwePolyethylene terephthalate. Kugadziridza kwehutsi uye hydrodesulfuration yekugadzirwa kwepetroleum, iyo inoshandisa yakasanganiswa cobalt molybdenum aluminium oxides secatalyst, chimwe chinhu chakakosha. Cobalt nemakomponi ayo, kunyanya cobalt carboxylates (inozivikanwa secobalt sipo), yakanaka oxidation catalysts. Anoshandiswa mupendi, mavhanishi, neingi seanoomesa kuburikidza neoxidation yemamwe makomisheni. Iwo akafanana carboxylates anoshandiswa kuvandudza kunamatira kwesimbi kune rabha musimbi-belt radial matai.
Pigments uye mavara-
Pamberi pezana ramakore rechi 19, kushandiswa kwakanyanya kwecobalt kwaive se pigment. Kubva pakati pekugadzirwa kwe smalt, girazi reruvara rwebhuruu raizivikanwa. Smalt inogadzirwa nekunyungudusa musanganiswa weyakakangwa mineral smaltite, quartz uye potassium carbonate, ichipa rima rebhuruu silicate girazi iro rinokuyiwa mushure mekugadzirwa. Smalt yaishandiswa zvakanyanya kugadzira girazi uye se pigment yekupenda. Muna 1780 Sven Rinman akawana cobalt yegirini uye muna 1802 Louis Jacques Thénard akawana cobalt yebhuruu. Iwo maviri mavara cobalt bhuruu, cobalt aluminate, uye cobalt girini, musanganiswa wecobalt(II) oxide uye zinc oxide, akashandiswa se pigment yekupenda nekuda kwekugadzikana kwawo kwepamusoro. Cobalt yakashandiswa kupenda girazi kubvira Bronze Age.
Tsanangudzo
Simbi ine brittle, hard metal, yakaita sesimbi uye nickel pakuonekwa, cobalt ine magineti inopenya ingangoita zvikamu zviviri muzvitatu zvesimbi. Inowanzo kuwanikwa sechigadzirwa che nickel, sirivheri, lead, mhangura, uye iron ores uye iripo mune meteorites.
Cobalt inowanzo sanganiswa nedzimwe simbi nekuda kwesimba rayo remagineti risingajairiki uye rinoshandiswa mu electroplating nekuda kwekutaridzika kwayo, kuoma uye kuramba kune oxidation.
