Chemical Properties Ntawm Molybdenum

Nws yog qhov nyuaj heev rau molybdenum poob xya lossis yim electrons [4]. Qhov no txiav txim siab tias molybdenum yog tshuaj lom neeg ruaj khov. Nyob rau hauv chav tsev kub los yog tsis kub heev, molybdenum yog ruaj khov nyob rau hauv huab cua los yog dej. Molybdenum rhuab hauv huab cua, xim pib tig los ntawm dawb (xim) mus rau tsaus grey; kub nce mus txog 520 degree C, molybdenum pib maj mam oxidized, tsim Mo2O3; Kub nce mus txog 600 ° C thiab siab dua, molybdenum yog oxidized sai sai rau hauv MoO3. molybdenum rhuab mus rau 700 ~ 800 degree C hauv dej vapor yuav pib tsim MoO2, nws yuav raug rhuab ntxiv, molybdenum dioxide txuas ntxiv mus oxidize rau molybdenum trioxide. Molybdenum tuaj yeem tshwm sim nyob rau hauv cov pa ntshiab huv los tsim molybdenum trioxide. Ntau cov oxides ntawm molybdenum tau raug tshaj tawm, tab sis ntau yam yog cov tshuaj tiv thaiv nruab nrab es tsis yog cov theem thermodynamically ruaj khov.
