Kev ceev faj rau kev siv niobium crucibles
Thaum sivniobium crucibles, koj yuav tsum tau xyuam xim rau cov ntsiab lus hauv qab no:
Ua ntej siv, nws yuav tsum maj mam ci rau 500 degrees Celsius.
Ntxiv cov ntaub ntawv raws li lub peev xwm ntawm lub crucible, thiab tsis txhob squeezing nruj heev los tiv thaiv cov hlau los ntawm thermal expansion thiab tawg lub crucible.
Thaum tshem tawm cov hlau molten, nws yog qhov zoo tshaj kom rub nws tawm nrog rab diav thiab siv calipers tsawg li sai tau. Yog tias siv cov calipers thiab lwm yam cuab yeej siv, lawv yuav tsum ua raws li cov duab ntawm lub crucible kom tsis txhob muaj zog hauv zos thiab ua rau lub neej ua haujlwm luv.
Tsis txhob txau cov nplaim hluav taws muaj zog oxidizing ncaj qha mus rau lub crucible, uas yuav ua rau crucible raw cov ntaub ntawv oxidize thiab luv-lub neej.
