Molybdenum electrodesyog resistant rau kub, tab sis yuav hnov mob nrog oxygen ntawm qhov kub thiab txias. Thaum qhov kub nce mus txog 400 degree, molybdenum pib tsim molybdenum oxide (MoO) thiab molybdenum disulfide (MoO2), uas ua raws li qhov chaw ntawm molybdenum electrode, tsim ib txheej oxide thiab tiv thaiv ntxiv oxidation ntawm molybdenum electrode.
Thaum kub txog 500 degree ~ 700 degree, molybdenum pib oxidize rau molybdenum trioxide (MoO3). Nws yog cov roj tsis hloov pauv uas rhuav tshem cov txheej txheem tiv thaiv ntawm thawj oxide, tso cai rau qhov chaw tshiab nthuav tawm los ntawm molybdenum electrode mus txuas ntxiv oxidize, tsim MoO3. Xws li rov oxidation thiab volatilization ua rau molybdenum electrode yuav tsum tsis tu ncua corroded kom txog thaum nws puas tag.
