99.98% ntshiab Nb Crucible

Txoj kev tsim khoom ntawmniobium crucibleFeem ntau suav nrog cov kauj ruam hauv qab no:

Kev npaj cov khoom nyoos: Ua ntej, niobium fluoride thiab sodium hlau yuav tsum tau npaj ua cov tshuaj txo. Cov ntaub ntawv nyoos no yuav raug siv rau cov tshuaj tiv thaiv thermal txo tom qab.

Thermal txo cov tshuaj tiv thaiv: Hauv txoj kev txo cov tshuaj sodium thermal, niobium fluoride thiab sodium hlau yog thermally txo ntawm qhov kub siab.

Kev kho cov khoom: Tom qab cov tshuaj tiv thaiv tiav, cov reactants raug tshem tawm ntawm lub crucible, ntsev nyob rau hauv cov tshuaj tiv thaiv cov khoom yog ntxuav nrog dej, thiab ces cov niobium hmoov yog ntxuav nrog dilute nitric acid thiab 25% hydrofluoric acid kom tshem tawm impurities thiab txhim kho. lub purity.

Crucible manufacturing : Ntxiv rau qhov saum toj no-hais thermal txo txoj kev npaj niobium hmoov, kev tsim cov crucibles kuj suav nrog kev siv alumina ua cov khoom tseem ceeb los ua crucible embryos los ntawm cov txheej txheem tshwj xeeb. Ib txheej ntawm crucible txheej slurry yog tusyees coated rau sab hauv ntawm lub crucible. Tom qab cov txheej yog qhuav, high-temperature sintering yog ua los ua kom tiav cov khoom ntawm crucible.
