Niobium Hlau Description
Niobium yog ib qho lustrous, grey hlau nrog tsawg toxicity thiab zoo li tsis muaj kev cuam tshuam rau tarnish. Nws cov khoom tshwj xeeb raws li cov hlau reactive ua rau niobium coj tuaj yeem tswj tau, rov ua tau ntau yam xim thaum raug rau ntau qhov hluav taws xob hauv chav da dej hluav taws xob, txheej txheem hu ua anodization.
Niobium hlau yog dav siv rau steel, ceramics, electronics, nuclear zog industries, thiab superconductor technology.
SSC yog lub chaw muag khoom thoob ntiaj teb ntawm cov khoom zoo niobium hlau. Peb cov qauv hlau hlau qhov ntau thiab tsawg ntawm 0.2mm mus rau 3.0mm 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 hlau alloys thiab ntsuas qhov ntau thiab tsawg. Peb kuj tuaj yeem muab Qws sab nraum qhov no.
Peb kuj tsim niobium ua 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.
