Hoʻolako pololei ʻia ka hale hana niobium foil kiʻekiʻe me ke kumu kūʻai haʻahaʻa
Kūlana kiʻekiʻepepa niobiumhoʻolako i ke kūʻai pololei ʻana o ka hale hana me ke kumu kūʻai haʻahaʻa,
pepa niobium,
Wehewehe Huahana
Hoʻohana ʻia ka foil Niobium i: ka ʻoihana superconducting, ke kūpaʻa wela kiʻekiʻe, ka ʻoihana kūpaʻa corrosion, aerospace, lāʻau lapaʻau a me ka ʻoihana kemika, hoʻohana ʻia i ka hana ʻana o nā mea hoʻopili kanaka, a pēlā aku.
He metala hina ʻālohilohi ka Niobium he paramagnetic a pili ia i ka hui 5 ma ka papa periodic. ʻOi aku ka ductile o ka metala niobium kiʻekiʻe-maʻemaʻe, akā paʻakikī me ka piʻi ʻana o ka nui o ka haumia.
*Paʻa ka Niobium i ka lewa ma ka mahana o ka lumi, a ʻaʻole i hoʻopau piha ʻia i ka wā e wela ai i ka oxygen. Hoʻohui pololei ʻia me ka sulfur, nitrogen a me ke kalapona i ka mahana kiʻekiʻe, a hiki ke hana i nā mea hoʻohuihui me ka titanium, zirconium, hafnium a me ka tungsten. ʻAʻole ia e launa pū me nā waikawa inorganic a i ʻole nā kumu, ʻaʻole hoʻi e hoʻoheheʻe ʻia i loko o ka aqua regia, akā hiki ke hoʻoheheʻe ʻia i loko o ka waikawa hydrofluoric. ʻO nā kūlana hoʻoheheʻe o ka niobium he -1, +2, +3, +4 a me +5, ʻo ia hoʻi +5 ka hui paʻa loa.
