He aha nā ʻano like ʻole o ka niobium?

Aia ka Niobium ma nā ʻano isotope paʻa ʻelua: niobium-93 a me ka niobium-95. Loaʻa i kēia mau isotopes nā helu like ʻole o nā neutrons i loko o kā lākou nuclei, akā hōʻike lākou a pau i nā ʻano kemika like. Ma ke ʻano o kona ʻano aniani, hiki i ka niobium ke noho i nā ʻano like ʻole, me ka alpha a me nā pae beta, ma muli o ke ʻano wela a me ke kaomi.

Ma waho aʻe o kona ʻano elemental, loaʻa ka niobium i loko o nā pūhui like ʻole a me nā alloys. No ka laʻana, hoʻohana mau ʻia ka niobium-tin (Nb3Sn) a me ka niobium-titanium (Nb-Ti) no ka hana ʻana i ka uea superconducting no nā noi e like me nā mīkini MRI a me nā mea wikiwiki. Hōʻike kēia mau alloys i nā waiwai superconducting i nā haʻahaʻa haʻahaʻa, e hoʻolilo iā lākou i mea waiwai ma ke kahua o ka superconductivity.

Eia kekahi, hiki ke hoʻohui ʻia ka niobium me nā metala ʻē aʻe e hoʻomaikaʻi i kāna mau waiwai no nā noi kikoʻī. No ka laʻana, hiki ke hoʻohui ʻia ka niobium me ka zirconium, tantalum a i ʻole nā mea ʻē aʻe e hana i nā alloys me ka ikaika i hoʻomaikaʻi ʻia, ke kūpaʻa corrosion a i ʻole nā waiwai superconducting.

Ma keʻano holoʻokoʻa, ʻo nā ʻano like ʻole o ka niobium e pili ana i kona ʻano elemental, isotopes, nā hale aniani, a me nā ʻāpana like ʻole a me nā pūhui, kēlā me kēia me nā waiwai a me nā noi.

Pehea ka hana ʻana o ka niobium?

Loaʻa ka Niobium ma o ke kaʻina hana i kapa ʻia ʻo Brazilian pyrochlore method. ʻO ke kaʻina hana unuhi e pili ana i kekahi mau pae:

1. Mining: ʻO ka hana mua e pili ana i ka unuhi ʻana i nā ores me ka niobium, i hui pinepine ʻia me nā minerale ʻē aʻe e like me tantalum, tin a me titanium. ʻO Brazil a me Kanada nā mea hana nui o ka niobium ore.

2. Loaʻa i ka ʻai: Hoʻomaʻamaʻa ʻia ka ʻaila i hoʻopaʻa ʻia i nā minerala niobium. ʻO kēia ka mea maʻamau e pili ana i ka ʻoki ʻana, ka wili ʻana a me nā ʻano hana hoʻokaʻawale like ʻole e hoʻokaʻawale i nā minerala i loko o ka niobium mai nā ʻāpana ʻē aʻe o ka ʻai.

3. Hoʻomaʻemaʻe: Hoʻomaʻemaʻe hou ka niobium ore i nā kaʻina hana e wehe i nā haumia a hana i ka niobium concentrate kiʻekiʻe. Hiki i kēia ke komo i ka hana kemika, ka leaching a me ka wehe ʻana i ka solvent no ka loaʻa ʻana o nā pūhui niobium maʻemaʻe.

4. Hoʻemi: Hoʻemi ʻia ka hui niobium i hoʻomaʻemaʻe ʻia i ka niobium metallic ma o ke kaʻina hana wela kiʻekiʻe, e hoʻohana maʻamau i nā ʻenehana e like me ke kaʻina hana hoʻemi aluminothermic. ʻO kēia ka hopena i ka hana ʻana o ka metala niobium ma ke ʻano pauka.

5. Hoʻohui: Hoʻohui ʻia ka pauka niobium i kahi ʻano paʻa ma o nā kaʻina hana e like me ka pauka metallurgy, forging a i ʻole nā hana hana ʻē aʻe e hana ai i nā niobium ingots, nā lau a i ʻole nā ʻano ʻē aʻe i makemake ʻia.

Ma keʻano holoʻokoʻa, ʻo ka hana ʻana o ka niobium e pili ana i nā ʻanuʻu e unuhi, hoʻomaʻemaʻe a hoʻomaʻamaʻa i nā ores i loaʻa i ka niobium no ka loaʻa ʻana o ka metala niobium maʻemaʻe kiʻekiʻe no ka hoʻohana ʻana i nā ʻano hana ʻenehana.
