Molybdenum paub txog nws cov thermal stability zoo heev thiab tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj melting lossis deforming. Qhov kub siab tshaj plaws uas molybdenum crucible tuaj yeem tiv taus yog nyob ntawm ntau yam xws li crucible qhov ntev, purity, thiab cov ntawv thov tshwj xeeb uas nws tau siv rau.
Feem ntau, molybdenum crucible tuaj yeem tiv taus qhov kub txog li 2, 000 degree (3,632 degree F) hauv lub tshuab nqus tsev lossis cua tsis zoo. Txawm li cas los xij, nyob rau hauv lub xub ntiag ntawm oxygen los yog lwm yam reactive gases, qhov siab tshaj plaws kub yuav qis dua. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kub siab tshaj plaws kuj tseem nyob ntawm qhov ntev ntawm qhov kub thiab txias.
Nws raug nquahu kom sab laj nrog peb txog molybdenum crucible los txiav txim siab qhov kub siab tshaj plaws uas nws tuaj yeem tiv taus rau ib daim ntawv thov tshwj xeeb. Cov chaw tsim khoom lossis tus neeg muag khoom tuaj yeem muab cov ntaub ntawv ntawm qhov tsim nyog qhov kub thiab txias thiab lwm yam kev qhia tshwj xeeb rau lub crucible.
Lub molybdenum crucible ua li cas thiab qhov purity ntawm cov khoom siv yog dab tsi?
Molybdenum crucibles feem ntau yog ua los ntawm kev siv cov hmoov metallurgy txheej txheem, uas muaj kev sib xyaw molybdenum hmoov nrog tus neeg sawv cev khi thiab tom qab ntawd compressing qhov sib tov rau hauv qhov xav tau. Cov hmoov compacted yog ces sintered ntawm qhov kub thiab txias los tsim ib qho khoom thiab ntom molybdenum crucible.
Molybdenum crucibles kuj tseem tuaj yeem ua los ntawm forging lossis spinning, qhov twg molybdenum pas nrig lossis daim ntawv yog zoo li tus rau hauv daim ntawv xav tau siv cua sov thiab siab. Txawm li cas los xij, cov txheej txheem no tsis tshua muaj ntau dua li hmoov metallurgy.
Lub purity ntawm molybdenum siv los ua crucibles tuaj yeem sib txawv nyob ntawm daim ntawv thov tshwj xeeb. Molybdenum nrog purity ntawm 99.95 feem pua los yog siab dua yog feem ntau siv los ua crucibles rau high-temperature applications hauv semiconductor, aerospace, thiab nuclear industries.
Rau qee yam kev siv, yuav tsum muaj kev ua kom huv siab dua molybdenum, thiab cov chaw tsim khoom tuaj yeem muab cov crucibles ua los ntawm ultra-high purity molybdenum nrog rau kev purity txog li 99.999 feem pua.
Lub purity ntawm molybdenum siv los ua crucibles yog ib qho tseem ceeb vim hais tias impurities tuaj yeem cuam tshuam rau cov khoom siv thiab corrosion tsis kam ntawm crucible, nrog rau cov kab mob ntawm cov khoom ua tiav hauv crucible.
