Pale grey ine yero tint. Hukama hwehukama 8.47I Inonyungudika poindi 2300 ℃; Kuchena kwekuumbwa -237.8kj / mol; Mohs kuomarara 8, micro kuomarara 14.3GPA; Kugadzikana 200U. Cm. Yayo superconducting shanduko yakakosha tembiricha iri 15.6 K. Insoluble muhydrochloric acid, nitric acid uye sulfuric acid; Inonyungudika muhydrofluoric acid uye sulfuric acid yakanyatsogadziriswa mhinduro, zvakare inogadzikana mune inopisa base kana yakakwira yeakisi alkaline, uye kusunungura ammonia.
Se carbide inowedzera, yakachena kuchena niobium inogona kuwanikwa. Kana yatsva kusvika 500 ~ 800 ℃ mumhepo, niobium pentoxide inoumbwa uye nitrogen inosunungurwa. Niobium nitride yakaora kuita niobium simbi muvharumu. Niobium nitride uye titanium carbide, zirconium carbide, vanadium carbide, tantalum oxide, nezvimwe zvinogona kugadzira mhinduro yakasimba.
Chaizvoizvo B-1 makomputa. Sodium chloride kristaro chimiro. Iyo inotonhora tembiricha ye superconductivity ndeye 17.3K. Iyo yepamusoro yakaoma magnetic field ndeye 43T. Iyo yakakosha yazvino density density Jc, (4.2K, 20T) inosvika ku2 × 106A / cm2. Yakakwira Thermal kugadzikana uye kugadzikana kwemakemikari, anti-neutron irradiation, yakanakisa superconducting yakatetepa firimu zvinhu. Iko kusanganiswa kweArgon uye nitrogen kwakagadzirwa nenzira yekuputika. Iyo inoshandiswa kugadzira yakanyatsogadzika superconducting quantum chiridzwa zvishandiso uye electrode zvinhu.
