Niobium Qws Description
SSC tshwj xeeb hauv kev tsim cov purity siab zoo zoo li tus niobium pas nrig thiab bar nrog qhov siab tshaj plaws ua tau thiab qhov tsawg tshaj plaws qhov nruab nrab cov qoob loo siv rau hauv semiconductor, Chemical Vapor Deposition (CVD) thiab Physical Vapor Deposition (PVD) cov txheej txheem suav nrog Thermal thiab Electron Beam (E- Beam) evaporation, Tsawg kub Organic evaporation, Atomic Layer Deposition (ALD), Metallic-Organic thiab Chemical Vapor Deposition (MOCVD). Peb tus qauv pas nrig thiab qhov ntau thiab tsawg ntawm 3mm mus rau 150mm inch. Peb tseem tuaj yeem muab cov pas nrig thiab bar sab nraum qhov ntau thiab tsawg ntawm cov ntaub ntawv tso tawm rau cov ntawv thov tshwj xeeb xws li roj hlwb thiab lub hnub ci zog thiab rau nyias zaj duab xis tso rau ntawm iav lossis hlau substrates. Cov ntaub ntawv yog tsim los ntawm crystallization, khoom lub xeev thiab lwm yam ultra siab purification txheej txheem xws li sublimation. 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. SSC pov tseg ib qho ntawm cov hlau tsis tshua muaj hauv ntiaj teb thiab feem ntau lwm yam khoom siv siab heev rau hauv pas nrig, bar, lossis phaj daim ntawv, nrog rau lwm cov duab uas tau tsim thiab los ntawm lwm cov txheej txheem xws li nanoparticles thiab hauv daim ntawv ntawm kev daws teeb meem thiab organometallics. Peb muaj ntau hom pwm pwm rau pas nrig thiab bar.
Niobium hmoov, ingot, pieces, pellets, disc, granules, hlau, compounds, yog tag nrho cov muaj nyob rau ntawm SSC.
