I. MISS siv thiab ua haujlwm ntawm Molybdenum
Molybdenum yog ib qho silvery - dawb nws yog xim hlau thiab tshuaj lom neeg, ua rau nws dav siv hauv ntau thaj teb. Hauv qab no yog cov siv tseem ceeb thiab kev ua haujlwm ntawm Molybdenum:
1. Kev lag luam hlau: Molybdenum dominates cov steel kev lag luam, suav rau kwv yees li 80% ntawm tag nrho molybenum noj. Nws txhim kho cov hlau lub zog, hardness, hnav tsis kam, thiab corrosion tsis kam, ua rau muaj kev ua tau zoo dua thiab lub neej kev ua haujlwm ntev dua. Piv txwv li, molybdenum -} muaj cov hlau stainless yog dav siv nyob rau hauv cov tshuaj lom neeg ib puag ncig xws li cov tshuaj lom neeg thiab kev lag luam marin.
2. Tshuaj Kev Lag Luam: Molybdenum tebchaw tau siv dav siv raws li catalysts hauv kev lag luam tshuaj lom neeg. Piv txwv li, molybdenum disulfide tuaj yeem siv ua catalystulfurization, thaum molybdenum oxide siv hauv kev tsim khoom ntawm ntau cov xim thiab dyes.
3. Electronics Kev Lag Luam: Molybdenum yog feem ntau siv los ua cov khoom electrode hauv kev lag luam hluav taws xob. Vim nws siab - kub ruaj khov thiab zoo siv hluav taws xob cov khoom siv xws li hluav taws xob cov leeg, cov tensorsors, thiab rectifiers. Molybdenum tseem siv nyob rau hauv kev tsim cov cua sov cov ntsiab thiab cov tshuab hluav taws kub hauv cov tshuab nqus tsev.
Ii. Cov kauj ruam tseem ceeb ntawm Molybdenum nyob rau hauv cov khoom lag luam semiconductor
Nrog kev nce qib sai ntawm semiconductor thev naus laus zis, kev thov ntawm Molybdenum hauv daim teb no tau dhau los ua ntau zuj zus. Hauv qab no yog peb qhov tseem ceeb thov cov kauj ruam rau molybdenum hauv semiconductor raug:
1. Ion imgantation: Hauv cov txheej txheem no, molybdenum yog siv los ua ion qhov khoom siv. Ion immantation yog ib txoj kev ntawm kev qhia dopant dog rau hauv Silicon Wafers, uas tuaj yeem hloov WAFER's Conductivity. Vim nws lub siab melting taw tes thiab zoo heev corrosion tsis kam, molybdenum tuaj yeem tiv thaiv cov tshuaj tiv thaiv ntawm cov pa roj av thiab yaig los ntawm cov chaw ruaj khov thiab ua haujlwm ntawm ion immilitation.
2. Molecular nqaj echitaxy khoom: molecular nqaj ecitaxy yog qhov siab {1} - zoo semiconductor cov khoom siv cov khoom siv thev naus laus zis. Hauv cov txheej txheem no, molybdenum yog siv raws li cov khoom siv rau baffles, cov tuav pov tseg, thiab lwm yam nyob hauv lub tshuab nqus tsev. Vim nws lub siab tawv thiab tiaj, molybdenum ntseeg tau qhov tseeb thiab xwm yeem ntawm cov semiconductor siv lead ua qauv.
3. Photolithography Daim Duab: Thaum lub Postolithography cov txheej txheem, cov khoom siv tau siv los ua lub npog ntsej muag los tiv thaiv qee thaj chaw ntawm cov thawv uas muaj wafer. Molybdenum ntawv ci yog dav siv ua lub photolithogy daim npog ntsej muag vim nws qhov siab precision, siab rov ua dua, thiab zoo heev corrosion.
