Putsoa e boputsoa bo bosehla. A lekanyelitsoeng segokanyipalo 8.47I qhibiliha ntlha 2300 ℃; Mocheso oa sebopeho -237.8kj / mol; Mohs thatafala 8, micro thatafala 14.3GPA; Phomolo ea 200U. Cm. Mocheso oa eona o fetohang o phahameng haholo ke 15.6 K. Ha e kenelle ka hydrochloric acid, nitric acid le sulfuric acid; E qhibiliha ka asiti ea hydrofluoric le sulfuric acid, e qhibilihang botlaaseng bo chesang kapa alkaline e phahameng, ebe e lokolla ammonia.
Ha e le tlatsetso ea carbide, niobium e phahameng e ka fumaneha hape. Ha e futhumetse ho fihla ho 500 ~ 800 ℃ moeeng, niobium pentoxide e thehoa ebe ho lokolloa naetrojene. Niobium nitride e senyehile ka tšepe ea niobium e lephaka. Niobium nitride le titanium carbide, zirconium carbide, vanadium carbide, tantalum oxide, jj e ka theha tharollo e tiileng.
Metsoako e tloaelehileng ea B-1. Sebopeho sa kristale ea sodium. Mocheso o mahlonoko oa tšebetso e phahameng ea motlakase ke 17.3K. Matla a phahameng a khoheli a matla ke 43T. Boima ba hona joale ba bohlokoa Jc, (4.2K, 20T) e ka fihla ho 2 × 106A / cm2. Botsitso bo phahameng ba mocheso le botsitso ba lik'hemik'hale, anti-neutron irradiation, lisebelisoa tse ntle haholo tsa filimi. Motsoako oa argon le naetrojene o ne o lokisitsoe ka mokhoa oa ho lutla. E sebelisetsoa ho etsa lisebelisoa tse tsitsitseng haholo tsa lisebelisoa tsa lisebelisoa tse ngata le lisebelisoa tsa eleketrode.
