Taw qhia rau cov khoom ntawm cov khoom siv Molybdenum
Molybdenum phiajCov ntaub ntawv muaj cov yam tseem ceeb cov khoom muaj xws li lub siab melting taw tes, zoo hluav taws xob thiab thermal conductivity, thiab muaj zog tshuaj ruaj khov.
Lub ntsiab lus melting ntawm Molybdenum cov ntaub ntawv yog li 2623 degree. Qhov no zoo melting points ua rau lawv tswj hwm cov kev ruaj ntseg hauv cov khoom siv kub siab heev, ua rau lawv zoo tshaj cov khoom ua haujlwm siab.
Tsis tas li ntawd, Molybdenum lub hom phiaj cov ntaub ntawv nthuav qhia zoo corrosion tsis zoo nyob rau hauv ntau ib puag ncig ib puag ncig. Qhov kev ruaj ntseg tshuaj muaj zog no yog qhov tseem ceeb rau lub sijhawm ntev ruaj ruaj thiab kev ua tau ntawm cov yeeb yaj kiab nyias.
Molybdenum cov ntaub ntawv kuj muaj qhov ntom ntom ntom ntom thiab tawv tawv, nrog rau cov khoom siv hluav taws xob tsawg. Cov yam ntxwv no ua rau lawv los tswj qhov seem ruaj khov thaum lub sijhawm tsim kev tsim khoom thiab txhim kho kev ua haujlwm ntawm cov khoom kawg.
Lub hom phiaj ntawm Molybdenum cov ntaub ntawv feem ntau yog ntau heev, ncav 99.9% lossis 99.99%, lossis siab dua. Lub siab purity ua kom cov kev ua tau zoo ntawm cov yeeb yaj kiab sputtered.
