Cov khoom zoo ntawmniobium crucibleFeem ntau suav nrog cov hauv qab no:
Kev ua haujlwm siab kub thiab tshuaj lom neeg ruaj khov: Niobium crucible muaj qhov kub thiab txias ua haujlwm zoo thiab tshuaj lom neeg ruaj khov. Txij li thaum lub melting point ntawm niobium yog siab li 2468 degree, niobium crucible yuav siv tau nyob rau hauv kub kub yam tsis muaj deformation. Tsis tas li ntawd, niobium crucible muaj qhov zoo oxidation tsis kam thiab corrosion kuj ntawm qhov kub thiab txias, thiab tuaj yeem nyob ruaj khov hauv ntau qhov chaw tshuaj lom neeg.
Lub cev muaj zog: Niobium crucible muaj lub cev zoo heev, siab ceev (8.57 g / cm3) thiab zoo thermal expansion coefficient, uas ua rau nws ua tau zoo nyob rau hauv ib puag ncig kub.
Daim ntawv thov dav: Niobium crucible yog dav siv hauv kev sim kub thiab kev ua metallurgical thiab lwm yam haujlwm. Hauv kev sim kub siab, niobium crucibles tuaj yeem siv los ua kom sov thiab yaj ntau yam hlau, alloys thiab lwm yam ntaub ntawv. Hauv kev ua metallurgical, niobium crucibles yog siv los ua cov hlau, hlau, cov hlau tsis-ferrous, thiab lwm yam.
