Pālehu hina me ka melemele. Ka nui pilina 8.47I kiko hoʻoheheʻe 2300 ℃; Ka wela o ka hoʻokumu -237.8kj / mol; Mohs paakiki 8, anakahi iki paakiki 14.3GPA; Resistivity 200U. Cm. ʻO kāna superconducting hoʻololi hoʻololi o ka mahana wela he 15.6 K. ʻAʻole hiki ke hoʻohana ʻia i loko o ka waikona hydrochloric acid, nitric acid a me sulfuric acid Hiki ke hoʻoheheʻe ʻia i ka waikū hydrofluoric a me ka sulfuric acid concentrated solution, a hiki ke hoʻoheheʻe ʻia i ke kumu wela a i ʻole ke kiʻina kiʻekiʻe o ka alkaline, a hoʻokuʻu i ka amonia.
Ma ke ʻano he hoʻohui hoʻohui carbide, hiki ke loaʻa i ka niobium maʻemaʻe kiʻekiʻe. Ke hoʻomehana ʻia i 500 ~ 800 ℃ i ka lewa, hoʻokumu ʻia ka niobium pentoxide a hoʻokuʻu ʻia ka nitrogen. Hoʻopau ʻia ʻo Niobium nitride i metala niobium i ka holo. Niobium nitride a me titanium carbide, zirconium carbide, vanadium carbide, tantalum oxide, a me nā mea ʻē aʻe hiki ke hana i kahi hopena paʻa.
Nā pūhui B-1 maʻamau. ʻO ka hana aniani Sodium chloride. ʻO ka wela nui o ka superconductivity ʻo 17.3K. ʻO ka mākēneki koʻikoʻi koʻikoʻi kiʻekiʻe ʻo 43T. ʻO ka mānoanoa koʻikoʻi o kēia manawa Jc, (4.2K, 20T) a i 2 × 106A / cm2. ʻO ke kūpaʻa wela kiʻekiʻe a me ka paʻa paʻa kemika, anti-neutron irradiation, maikaʻi superconducting lahilahi nā mea kiʻi ʻoniʻoni. Hoʻomākaukau ʻia ka hui ʻana o ka argon a me ka naikokene e ka hana sputtering. Hoʻohana ʻia ia no ka hana ʻana i nā lako hana mea nui kuantum superconducting kuantum a me nā pono uila uila.
