Molybdenum yog ib qho tseem ceeb me me me me nrog ntau cov ntawv thov. Txawm li cas los xij, ntawm chav tsev kub, molybdenum reacts nrog oxygen nyob rau hauv huab cua los ua oxides. Txawm hais tias qhov txheej txheem oxidation no qeeb, nws muaj qhov cuam tshuam tseem ceeb ntawm nws cov khoom thiab kev siv.
I. Molybdenum oxidation mechanism
Nyob rau ntawm chav tsev kub, molybdenum reacts nrog oxygen los ua molybdenum oxides. Cov txheej txheem no feem ntau cuam tshuam los ntawm cov lus xws li kub, av noo, thiab oxygen concentration. Raws li cov tshuaj tiv thaiv taus, cov yeeb yaj kiab ntom nti maj mam nce ntawm Molybdenum saum npoo av, uas txwv tsis pub ntxiv oxidation ntawm molybdenum nyob rau hauv. Txawm li cas los xij, nrog ntev ntev raug rau huab cua lossis siab av noo, oxide zaj duab xis yuav maj mam tawg, ua rau kev ua kom loj oxidation.
Ii. Yam cuam tshuam rau molybdenum oxidation
1. Kub: Txawm hais tias tus lej oxidation ntawm Molybdenum yog qeeb ntawm chav sov, nws nrawm nrog nce kub. Yog li ntawd, molybdenum oxidation dhau los ua ntau qhov tseem ceeb hauv high -} qhov chaw ib puag ncig.
2. Voj av noo: Vaum muaj kev cuam tshuam tseem ceeb ntawm Molybdenum oxidation. Nyob rau hauv ib puag ncig huab cua, dej vapor reacts nrog oxide ntawm molybdenum saum npoo los ua soluble molybdates, uas nrawm rau cov txheej txheem oxidation.
3. Oxygen Conctrtration: Qhov Ntau Dua Cov Oxygen Conctrtration, nrawm dua tus mob oxidation ntawm molybdenum. Yog li ntawd, nyob rau hauv lub kaw los yog qis - pa oxygen ib puag ncig, tus nqi oxidation ntawm molybdenum tau qeeb.
3. Cov khoom ntawm Molybdenum oxide
Molybdenum oxide feem ntau ua rau cov xim sib txawv sib txawv thiab cov khoom siv lub cev, nyob ntawm seb cov qib ntawm oxidation thiab cov xwm txheej. Feem ntau hais lus, molybdenum oxide muaj siab tawv thiab melting point, nrog rau cov tshuaj ruaj khov zoo. Txawm li cas los xij, nyob rau qee yam kev mob, xws li kub siab lossis muaj zog acidic ib puag ncig, molybdenum oxide tej zaum yuav decompose los yog hnov mob nrog lwm yam tshuaj.
