Cov hlau no tau ua kom nws txoj haujlwm ruaj khov hauv cov chaw ib txwm muaj, xws li superalloys, thiab tau pom tias muaj kev siv ntau dua hauv qee qhov kev siv tshiab, xws li hauv cov roj teeb rov qab tau.
Cov hlau nplaum-
Cov superalloys uas muaj cobalt siv feem ntau ntawm cov cobalt uas tsim tawm. Qhov kub thiab txias ntawm cov alloys no ua rau lawv tsim nyog rau kev siv hauv cov hniav turbine rau cov roj turbines thiab cov cav dav hlau, txawm hais tias cov alloys uas muaj nickel ua ib leeg siv lead ua ke ntau dua li lawv hauv qhov no. Cov alloys uas muaj cobalt kuj tiv taus xeb thiab hnav-resistant. Cov alloys cobalt-chromium-molybdenum tshwj xeeb yog siv rau cov khoom prosthetic xws li hloov lub duav thiab lub hauv caug. Cov alloys Cobalt kuj tseem siv rau cov hniav prosthetics, qhov twg lawv muaj txiaj ntsig zoo kom tsis txhob ua xua rau nickel. Qee cov hlau ceev ceev kuj siv cobalt los ua kom sov thiab hnav-resistant. Cov alloys tshwj xeeb ntawm txhuas, nickel, cobalt thiab hlau, hu ua Alnico, thiab ntawm samarium thiab cobalt (samarium-cobalt magnet) yog siv rau hauv cov hlau nplaum tas mus li.
Cov roj teeb-
Lithium cobalt oxide (LiCoO2) yog siv dav hauv cov electrodes roj teeb Lithium ion. Cov roj teeb nickel-cadmium (NiCd) thiab nickel metal hydride (NiMH) kuj muaj cov cobalt ntau heev.
Catalyst-
Muaj ntau cov cobalt sib xyaw siv rau hauv cov tshuaj lom neeg ua cov catalysts. Cobalt acetate siv rau kev tsim cov terephthalic acid nrog rau dimethyl terephthalic acid, uas yog cov sib xyaw tseem ceeb hauv kev tsim cov Polyethylene terephthalate. Kev hloov pauv pa thiab hydrodesulfuration rau kev tsim cov roj av, uas siv cov cobalt molybdenum txhuas oxides sib xyaw ua cov catalyst, yog lwm daim ntawv thov tseem ceeb. Cobalt thiab nws cov sib xyaw, tshwj xeeb tshaj yog cobalt carboxylates (hu ua cobalt xab npum), yog cov catalysts oxidation zoo. Lawv siv rau hauv cov xim, varnishes, thiab inks ua cov neeg sawv cev ziab los ntawm kev oxidation ntawm qee cov sib xyaw. Tib cov carboxylates siv los txhim kho qhov kev nplaum ntawm cov hlau rau roj hmab hauv cov log tsheb radial uas siv hlau.
Cov xim thiab cov pigments -
Ua ntej xyoo pua 19th, kev siv cobalt feem ntau yog ua xim. Txij li thaum nruab nrab ntawm kev tsim cov smalt, ib lub iav xiav tau paub. Smalt yog tsim los ntawm kev yaj cov khoom sib xyaw ntawm cov zaub mov smaltite, quartz thiab potassium carbonate, ua rau cov iav xiav tsaus uas raug sib tsoo tom qab tsim khoom. Smalt tau siv dav rau kev pleev xim rau iav thiab ua xim rau cov duab pleev xim. Xyoo 1780 Sven Rinman tau tshawb pom cobalt ntsuab thiab xyoo 1802 Louis Jacques Thénard tau tshawb pom cobalt xiav. Ob xim cobalt xiav, cobalt aluminate, thiab cobalt ntsuab, sib xyaw ntawm cobalt (II) oxide thiab zinc oxide, tau siv ua cov xim rau cov duab pleev xim vim lawv qhov ruaj khov zoo. Cobalt tau siv los pleev xim iav txij li Lub Caij Nyoog Tooj Liab.
Kev piav qhia
Ib hom hlau tawv, nkig thiab tawg yooj yim, zoo li hlau thiab nickel, muaj qhov permeability magnetic kwv yees li ob feem peb ntawm hlau. Nws feem ntau tau los ua cov khoom seem ntawm nickel, nyiaj, txhuas, tooj liab, thiab hlau ores thiab muaj nyob rau hauv cov hnub qub poob.
Cobalt feem ntau yog sib xyaw nrog lwm cov hlau vim nws lub zog sib nqus tsis tshua muaj thiab siv rau hauv electroplating vim nws qhov tsos, qhov nyuaj thiab kev tiv thaiv oxidation.
