Lub luag haujlwm ntawm Tantalum Crucibles hauv Electron Beam Evaporation
Tantalum crucibles rau E-beam qhov chaw yog precision-engineered containers siv nyob rau hauv electron beam evaporation systems, uas siab thermal stability thiab ultra-low outgassing yog ib qho tseem ceeb los tswj lub tshuab nqus tsev thiab deposit purity.
Nyob rau hauv E-beam deposition, ib tug tsom electron beam vaporizes cov khoom nyob rau hauv lub crucible, thiab resultant vapor condenses mus rau substrates raws li nyias films. Tantalum raug xaiv vim nws qhov siab melting point tso cai rau evaporation ntawm refractory hlau (xws li, W, Mo, Ta nws tus kheej) thiab oxides yam tsis muaj crucible tsis ua hauj lwm. Nws qis vapor siab ntawm kev ua haujlwm kub (<10⁻⁸ Pa at 2500 °C) prevents crucible material from contaminating the deposited film. Additionally, tantalum's low outgassing rate (<10⁻⁹ Torr·L/s·cm²) helps sustain UHV conditions (<10⁻⁷ Pa) crucial for high‑performance optics and semiconductor coatings.

Kev txiav txim siab tsim qauv rau E-Beam Tantalum Crucibles
Cov Crucibles yog tsim los nrog cov phab ntsa nyias (1-3 hli) kom ua kom sov siab tshaj plaws los ntawm cov kab hluav taws xob thaum txo qis cov khoom siv thermal. Geometry feem ntau yog cylindrical nrog puag ncig hauv qab kom tsis txhob muaj cov kaum ntse ntse uas cov khoom molten tuaj yeem stagnate lossis overheat hauv zos. Txhawm rau tiv thaiv kev puas tsuaj los ntawm siab - hluav taws xob hluav taws xob, qee qhov qauv tsim siv cov tsho dej txias los yog siv cov khoom siv nrog cov khoom siv ua kom zoo nkauj los faib cov hluav taws xob sib npaug.
Kev Siv Khoom Siv Rau E-Beam Tantalum Crucibles
Optical Txheej- Evaporation ntawm TiO₂, Al₂O₃, thiab SiO₂ rau lo ntsiab muag thiab laser tsom iav yuav tsum muaj siab refractive index tswj.
Microelectronics- Kev tso tawm ntawm cov txheej thaiv txheej (piv txwv li, TaN) thiab cov hlau sib txuas uas purity ncaj qha cuam tshuam cov cuab yeej kev ntseeg tau.
Zaub Technology- Uniform evaporation ntawm indium tin oxide (ITO) rau pob tshab conductive txheej.
Lawv compatibility nrog automated feed systems thiab lub neej ua haujlwm ntev ua rau lawv tus qauv nyob rau hauv high-throughput txheej chambers rau architectural iav, precision optics, thiab advanced electronic substrates.
