Tantalum Hlau Description
SSC tshwj xeeb hauv kev tsim cov purity siab zoo zoo li tantalum hlau nrog qhov ua tau zoo tshaj plaws. Tantalum hlau yog ua los ntawm hlau tantalum. Hlau fabrication pib nrog tantalum ingot, uas yog tsim los ntawm tantalum seem los yog mined tantalum minerals. Lub ingot loj yog txo nyob rau hauv ib tug xov tooj ntawm cov kauj ruam xaus los ntawm kev kos duab ntawm tantalum. Peb feem ntau muab electron beam melted Qib R05200 los yog sintered tantalum Qib R05400 khoom.
Tantalum tau siv rau ntau xyoo lawm hauv cov khoom siv hluav taws xob, feem ntau yog hmoov thiab xaim rau cov khoom siv hluav taws xob hauv qhov chaw-rhiab, kev siv high-end hauv kev sib txuas lus thiab cov ntaub ntawv khaws cia. Nyob rau hauv additon tantalum yog wiedely siv nyob rau hauv sputtering txheej txheem. Lub siab melting point, zoo thermal conductivity ntawm cov hlau refractory thiab nws tsis kam mus corrosion ua yog haum raws li thermal ntsiab nyob rau hauv cov ntaub ntawv nyuaj. Tantalum hlau yog cov khoom zoo tshaj plaws rau kev siv lub tshuab nqus tsev hauv kev lag luam teeb pom kev zoo. Tantalum hlau kuj tseem siv tau rau hauv kev tsim cov khoom cua sov, lub tshuab nqus tsev, thiab lwm qhov chaw kub.
Hlau ua los ntawm tantalum kuj tseem siv rau hauv cov khoom siv kho mob (xws li cov cim pins thiab cov pob) vim cov hlau muaj qhov ntom ntom ntom piv rau lwm cov hlau thiab cov khoom siv. Nws qhia tau meej heev ntawm (x-ray) xov tooj cua thiab muaj tus nqi qis dua li cov khoom muaj txiaj ntsig platinum.
Tantalum yog siv nyob rau hauv ntau yam ntawm lwm yam kev siv uas yuav tsum tau muaj zog, ductility, toughness, corrosion kuj, thermal conductivity thiab siab melting point. Hlau khoom nyob rau hauv annealed thiab txias ua hauj lwm tej yam kev mob ntawm 99.95 feem pua purity cov ntaub ntawv, los yog nrog alloy ntsiab xws li tungsten, titanium los yog molybdenum siv nyob rau hauv tshuaj lom neeg kev lag luam. Tantalum npib tsib xee alloys yog siv hauv kev siv aerospace. Thiab ntawm chav kawm, tantalum alloy cov ntaub ntawv tsim los kuj muaj nyob rau ntawm SSC.
Peb cov qauv hlau hlau qhov ntau thiab tsawg yog los ntawm {{0}}.1 hli mus rau 4.0 hli txoj kab uas hla nrog nruj tolerances thiab alpha qhov tseem ceeb (conductive resistance) rau kev siv xws li kev kuaj roj thiab ntsuas qhov ntsuas kub.
Thov hu rau peb los tsim kev cai alloy hlau thiab ntsuas qhov ntau thiab tsawg. Peb kuj tuaj yeem muab cov xaim tawm sab nraud peb cov qauv ntau. Peb kuj tsim tantalum li hmoov, ingot, pieces, pellets, disc, granules thiab nyob rau hauv cov ntaub ntawv compound, xws li oxide. Lwm cov duab muaj nyob ntawm kev thov.
