Tantalum Target 3N5

Tantalum lub hom phiaj, tantalum tshuaj cim Ta, steel grey hlau, nyob rau hauv lub periodic rooj ntawm VB pawg, atomic tooj 73, atomic hnyav 180.9479, lub cev center cubic siv lead ua, ntau valence yog ntxiv rau 5. Lub hardness ntawm tantalum yog tsawg thiab muaj feem xyuam rau cov pa oxygen. cov ntsiab lus, zoo tib yam ntshiab tantalum, annealed Vickers hardness tsuas yog 140HV. Nws muaj qhov melting point txog li 2995 degree, qeb thib tsib ntawm cov khoom tom qab carbon, tungsten, rhenium, thiab osmium.

Tantalum yog malleable thiab tuaj yeem kos rau hauv filament kom nyias nyias. Nws coefficient ntawm thermal expansion yog me me. Rau txhua qhov degree Celsius nce, nws tsuas yog nthuav tawm los ntawm 6.6 feem ntawm ib lab. Nws kuj tseem siv tau ntau dua li tooj liab. High-purity tantalum tuaj yeem siv los ua cov khoom siv hluav taws xob electrolytic capacitor nrog lub peev xwm loj, me me, thiab kev ua haujlwm ruaj khov, siv nyob rau hauv radar, missiles, supersonic aircraft, thiab electronic computers, tantalum kuj tseem tuaj yeem tsim petrochemical heat exchangers, heaters, concentrators, thiab reactors. tanks, towers, pipelines, thiab li qub.

Tantalum tseem tuaj yeem siv los ua lub tshuab xa hluav taws xob thiab cov khoom siv hluav taws xob siab, tantalum alloy tuaj yeem siv los ua lub tshuab hluav taws xob supersonic combustion chamber thiab cov ntaub ntawv kub-resistant thiab siab zog, tantalum tungsten alloy missile nozzle, tantalum carbide yuav siv tau. ib leeg los yog ua ke nrog lwm cov pa roj carbon monoxide, raws li ib tug forging tuag, tej cuab yeej, dav hlau cav turbine hniav, li qub, thiab foob pob ua ntxaij nozzle txheej.

Tantalum carbide yog siv dav hauv kev tsim cov cemented carbide. Tantalum kuj muaj kev ruaj ntseg thiab kho cov khoom nrog tib neeg cov ntaub so ntswg, thiab tuaj yeem siv los ua kev phais ntxiv thiab cov pob txha, nrog rau cov pob txha daim hlau, cov ntsia hlau, thiab cov koob suture.

Daim duab hauv qab no yog daim duab ntawm micrometallographic nrhiav pom ntawm lub hom phiaj tantalum sputtering, nrog qhov nruab nrab qhov loj me ntawm <100um.

Peb tsim cov hom phiaj tantalum 3N5, qhov txiaj ntsig tseem ceeb tshaj plaws uas yog lub peev xwm kom tau txais cov yeeb yaj kiab nrog kev ua tau zoo thiab kev ua kom tsawg tsawg thaum lub cev vapor deposition. Cov lus hauv qab no yog daim ntawv pov thawj kev txheeb xyuas muaj pes tsawg leeg ntawm tantalum phiaj 3N5. Txoj kev tsom xam tau txais: 1, kev siv ICP-OES los soj ntsuam cov ntsiab lus hlau; 2. Siv LECO rau kev txheeb xyuas cov khoom siv roj.
