Tantalum Lump Description
Tantalum yog cov hlau refractory uas yog ductile, yooj yim fabricated thiab heev tiv taus corrosion los ntawm acids. Nws kuj yog ib tug zoo conductor ntawm tshav kub, hluav taws xob thiab muaj ib tug siab melting point. Nws yog tshwj xeeb tshaj yog tiv taus cov tshuaj ntawm qhov kub thiab txias hauv qab 150 degree / 302℉ thiab tsuas yog yaj nrog hydrofluoric acid. Nyob rau hauv ntau yam alloys, tantalum yog siv los ntxiv zog, ductility, thiab siab melting point. Txog ib nrab ntawm kev siv tantalum yog rau electrolytic capacitors thiab cov khoom ntawm lub tshuab nqus tsev vacuum.
SSC tshwj xeeb hauv kev tsim cov purity siab tantalum pob nrog qhov siab tshaj plaws thiab qhov tsawg tshaj plaws qhov nruab nrab ntawm cov qoob loo siv rau hauv Chemical Vapor Deposition (CVD) thiab Physical Vapor Deposition (PVD) cov txheej txheem suav nrog Thermal thiab Electron Beam (E-Beam) Evaporation, Kub Kub. Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic thiab Chemical Vapor Deposition (MOCVD). Peb cov pob khoom txheem yog amorphous cov khoom sib xws hauv qhov ntau thiab tsawg ntawm 5-15 hli. Cov khoom siv pob zeb yog tsim los siv crystallization, khoom hauv lub xeev thiab lwm yam kev ua kom huv siab ultra siab xws li sublimation.
Peb kuj tsim tantalum li qws, pellets, hmoov, pieces, disc, ingot, hlau, thiab nyob rau hauv cov ntaub ntawv compound, xws li oxide. Lwm cov duab muaj nyob ntawm kev thov.
