Molybdenumyog ib qho tseem ceeb chemical. Nrog rau lub cim Mo thiab atomic tooj 42, nws yog ib tug silvery-dawb hlau nyob rau hauv lub periodic rooj ntawm lub ntsiab, teej tug mus rau lub venerable hloov hlau pawg.
Nws cov khoom tshwj xeeb, suav nrog qhov siab melting point thiab exceptional durability, ua rau nws haum rau ntau yam kev siv.
Cov khoom tseem ceeb no feem ntau yog muab rho tawm los ntawm molybdenite, ib qho ntxhia uas muaj molybdenum sulfide. Nws tsis yog qhov tsis yooj yim kom pom cov khoom no ua ke nrog lwm cov ntsiab lus hauv cov zaub mov thiab ores.
Molybdenum yog cais raws li cov hlau refractory, nrog lub melting point siab txog 2,623 degrees Celsius (4,753 degrees Fahrenheit). Xws li ib tug feat yog tiag tiag zoo kawg li, koj puas tsis pom zoo?
Tsis tas li ntawd, nws qhov ceev ntawm 10.28 grams ib cubic centimeter muab nws qhov hnyav uas muab nws sib nrug.
Txawm li cas los xij, txawm tias nws hnyav hnyav, molybdenum muaj cov thermal thiab hluav taws xob zoo heev, nrog rau cov coefficient tsawg ntawm thermal expansion. Xws li kev sib xyaw ua pov thawj nws cov khoom tshwj xeeb. Tsis tas li ntawd, nws tseem tawv nyob rau hauv lub ntsej muag ntawm corrosion thiab tsis kam ua nrog hydrochloric los yog sulfuric acid nyob rau hauv chav tsev kub.
