Txheej txheem cej luam ntawm cobalt tetroxide

Cobalt trioxide (Co3O4) yog ib qho khoom siv nrog lub cev thiab tshuaj lom neeg zoo heev.Nws yog cov khoom dub, insoluble hauv dej thiab ruaj khov rau huab cua thiab noo noo.Vim tias nws cov khoom sib nqus siab, cov tshuaj lom neeg muaj zog thiab kev ua haujlwm siab electrochemical, cobalt tetroxide tau siv dav hauv lub zog, hluav taws xob, catalysts thiab lwm yam.

Lub cev thiab tshuaj muaj zog ntawm cobalt trioxide

Cobalt tetroxide muaj lub cev zoo heev.Nws yog cov khoom dub, insoluble hauv dej thiab ruaj khov rau huab cua thiab noo noo ntawm chav tsev kub.Nws qhov ceev yog 5.12g / cm3, thiab cov muaju yog tetragonal oxides.Magnetism yog ib qho tseem ceeb ntawm cobalt tetroxide, uas muaj cov hlau nplaum siab thiab tuaj yeem siv rau hauv cov khoom sib nqus thiab lwm yam.

Hais txog cov khoom siv tshuaj, cobalt tetroxide muaj cov tshuaj lom neeg ua haujlwm siab.Nws tuaj yeem raug txo kom cobalt hlau lossis oxidized rau cobalt dioxide.Tsis tas li ntawd, cobalt tetroxide yuav decompose nyob rau hauv qhov kub thiab txias.

Kev tsim thiab kev tsim cov txheej txheem ntawm cobalt trioxide

Muaj ntau ntau txoj hauv kev ntawm cobalt tetroxide, cov txheej txheem tseem ceeb suav nrog cov theem khoom sib txuas, cov txheej txheem ua kua thiab cov roj theem synthesis.Ntawm lawv, cov txheej txheem synthesis yog cov txheej txheem feem ntau siv.Nws yog ua los ntawm cobalt hlau los yog cobalt hydroxide ua raw cov ntaub ntawv, thiab yog hlawv nyob rau hauv oxygen ntawm kub kub kom tau txais cobalt tetroxide.

Cov chaw siv tseem ceeb ntawm cobalt tetroxide

Vim nws cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, cobalt tetroxide tau siv dav hauv ntau qhov chaw.Ntawm lawv, daim ntawv thov tseem ceeb tshaj plaws yog thaj chaw catalyst.Cobalt tetroxide tuaj yeem siv los ua cov tshuaj tiv thaiv ntau yam, xws li cov tshuaj tiv thaiv cyclopropanation, cov tshuaj tiv thaiv oxidation, cov tshuaj tiv thaiv alkylation, thiab lwm yam. Tsis tas li ntawd, cobalt tetroxide kuj tuaj yeem siv rau hauv cov khoom siv roj teeb, cov khoom sib nqus, cov khoom siv hluav taws xob thiab lwm yam.
