Daim ntawv thov rau Cobalt chloride

Cobalt chloride muaj ntau yam kev siv. Nws yog siv nyob rau hauv hygrometers; raws li ib tug humidity qhia; raws li qhov ntsuas kub hauv kev sib tsoo; ua npuas ncauj stabilizer hauv npias; nyob rau hauv invisible number case; rau painting rau iav; hauv electroplating; thiab ib qho catalyst hauv Grignard cov tshuaj tiv thaiv, txhawb kev sib txuas nrog cov organic halide. Nws kuj yog siv los npaj ob peb lwm cov ntsev cobalt; thiab hauv kev tsim cov hluavtaws vitamin B12.
Lub vapor-theem co-txo nrog lwm cov hlau halides los ntawm hydrogen ua rau kev sib faib ua haujlwm zoo nrog cov ntaub ntawv siv los yog cov khoom sib txuas nrog cov khoom siv thermoelectric, sib nqus, thiab oxidation-resistance.
