Tungstenmolybdenum pas nrig
Molybdenum tsis tshwm sim raws li cov hlau dawb hauv ntiaj teb, tab sis tshwm sim hauv cov zaub mov hauv ntau lub xeev oxidation.
Cov khoom pub dawb no yog cov hlau silvery nrog grey cam khwb cia thiab muaj qhov thib rau siab tshaj plaws melting point ntawm tag nrho cov ntsiab lus.
Nws nkag tau yooj yim, ruaj khov carbides nyob rau hauv alloys, ntau ntawm lub ntiaj teb no cov khoom ntawm cov khoom no (kwv yees li 80%) yog siv los ua ntau hom hlau alloys, xws li high-strength alloys thiab high-temperature alloys.
Feem ntau cov molybdenum tebchaw muaj tsawg solubility nyob rau hauv dej, tab sis cov molybdate ion MoO42- yog soluble thiab cov ntaub ntawv thaum molybdenum-muaj minerals los rau hauv kev sib cuag nrog oxygen thiab dej.
Kev lag luam, molybdenum tebchaw (suav txog kwv yees li 14% ntawm lub ntiaj teb kev tsim khoom ntawm cov khoom no) yog siv nyob rau hauv high-pressure thiab high-temperature daim ntaub ntawv raws li pigments thiab catalysts.
