Ua ntej tshaj plaws, los ntawm kev xav ntawm cov khoom tsim,niobium cruciblesfeem ntau yog ua los ntawm niobium hlau cov ntaub ntawv, nrog ib puag ncig lossis square zoo li thiab nruab nrog lub hau thiab ob txhais ceg. Txij li thaum niobium crucibles yooj yim deform thaum siv ntawm qhov kub thiab txias, lawv cov hauv qab feem ntau thicker. Tsis tas li ntawd, niobium crucibles tuaj yeem ua rau ntau qhov ntau thiab tsawg thiab cov duab raws li kev siv sib txawv.
Tom ntej no yog cov lus nug ntawm yuav ua li cas xaiv cov khoom. Thaum xaiv niobium crucible, peb yuav tsum xav txog cov hauv qab no: ua ntej, qhov zoo ntawm lub crucible, nrog rau nws cov purity thiab kev ua tau zoo; thib ob, nws lub cev muaj zog, xws li ceev, thermal expansion coefficient, thiab lwm yam.; thib peb, tshuaj muaj zog, xws li corrosion kuj, oxidation kuj, thiab lwm yam .; Thaum kawg, kev siv cov xwm txheej, xws li kev siv qhov kub thiab txias, txawm tias yuav tsum tau kho kom haum, thiab lwm yam.
