Niobium Material Introduction

ʻO kā mākou mau pepa niobium ua ʻōwili ʻia a hoʻoheheʻe ʻia me ka hoʻohaʻahaʻa pono ʻana e hōʻoia i ka metallurgy kūpono.Ke nānā pono nei kēlā me kēia pepa no nā ana, ka pau ʻana o ka ʻili, a me ka palahalaha.

ʻO ka pepa Niobium ka metala refractory māmā loa (density 8.57 g/cc) a he wela hoʻoheheʻe kiʻekiʻe (2,468ºC).Hiki i kēia waiwai ke hāʻawi i kāna mau alaleʻa e hāʻawi i nā hoʻonā hoʻolālā i nā wela kiʻekiʻe: ʻoi aku ka kiʻekiʻe ma mua o 600ºC i nā nickel based alloys a hiki i ka 1,300ºC i nā alloys based niobium.

Loaʻa i ka pepa Niobium nā waiwai kino a me nā mea kemika e like me nā mea o ka tantalum element.Kū'ē ia i ka ʻino ʻana i ka hana ʻana i ke kiʻi ʻoniʻoni dielectric oxide.Hoʻomaka ka metala e oxidize wikiwiki i ka ea ma 200 ºC.

Ma lalo -264ºC, hōʻike ka niobium i nā waiwai superconducting.Ke alakaʻi nei ia i nā kiʻekiʻe kiʻekiʻe o ke kūʻē ʻole o ka uila, e hana ana i nā māla magnetic a me nā ikaika e hāʻawi i nā noi kūpono koʻikoʻi i nā wahi e like me ka diagnostics olakino, noiʻi waiwai a me ka halihali.
