Tantalum Foil thiab Sawb Description
Tantalum zoo nkaus li ci thiab silvery hlau nyob rau hauv nws daim ntawv mos thiab ntshiab. Cov hlau yog corrosion-resistant thiab yog khi rau tshuaj tua kab mob hauv qab 150 degree. Cov khoom no muaj ntau pom nyob rau hauv qhov zoo li uranium. Tantalum tau hais tias yog ib qho zoo heev conductor ntawm tshav kub & hluav taws xob. Nws muaj qhov siab melting point ntawm txog 3017 degree thiab kub kub ntawm txog 5458 degree. Sib nrug los ntawm hydrochloric acid, tantlum qhia tau hais tias zoo heev rau tag nrho cov acids nyob rau hauv ib txwm kub. Nws feem ntau tshwm nyob rau hauv lub ntxiv 5 oxidation lub xeev los nyob rau hauv nws cov tebchaw. Nws paub tias yog ib qho ntawm cov tshuaj inert muaj nyob hauv lub ntiaj teb.
Tantalum yog ductile heev thiab tuaj yeem ua tau yooj yim txias vim yog qhov ua haujlwm qis qis. Vuam tuaj yeem ua tiav los ntawm kev tiv thaiv, TIG, lossis electron beam txoj kev, nrog kev saib xyuas los tiv thaiv qhov vuam thiab tshav kub cuam tshuam los ntawm huab cua thaum vuam. Vim tias muaj peev xwm rau hydrogen embrittlement, Tantalum tsis tuaj yeem siv rau kev pabcuam txuas ntxiv hauv huab cua lossis lwm yam oxidizing cua saum toj 260 degree / 500℉ tshwj tsis yog muaj kev tiv thaiv inert cua lossis lub tshuab nqus tsev.
SSC tshwj xeeb hauv kev tsim cov kev cai sib xyaw rau kev lag luam thiab kev tshawb fawb daim ntawv thov thiab rau cov cuab yeej tshiab. Cov ntaub ntawv yog tsim los ntawm crystallization, khoom lub xeev thiab lwm yam ultra siab purification txheej txheem xws li sublimation. Tailor-made tantalum alloy cov ntaub ntawv, xws li tantalum tungsten alloy, tantalum niobium alloy kuj muaj nyob ntawm SSC.
Peb kuj tsim tantalum li pas nrig, pellets, hmoov, pieces, disc, granules, hlau, thiab nyob rau hauv cov ntaub ntawv compound, xws li oxide. Lwm cov duab muaj nyob ntawm kev thov.
