Niobium koa:-i? Iecaianoaaiiuo, ka waiwai, noi

Niobium - Nine Inch hehee ai me ka'ātoma helu 41. Ua Ua mua loaa i loko o ke kakahiaka XIX kenekulia, akā, iʻula a kona hoʻomaopopo pono no 150 makahiki. Wale i ka makahiki 1950, he malū aeea i loko o ka papa'āweʻaweʻa kemika papaʻaina i ua anao? Aou i ka olelo hooholo o ka Union o haʻapili International a me kaʻimi naʻauao kemika'Ātoma. E hoʻohana i ka pili me ka hehee ai i loko o ka hana, ka mea, ua i mai ka loloa o ka niobium. Ma ona iho, ka mea, aole e lilo i kekahi mea hanana. Ua hōʻike kona piha Loaʻaʻia ka wā e pili ana oka a, pāʻoihana a me nā mele.

pōʻalo o niobium

Niobium na mea i eliia enrichment - he loa eiiieaena, a pipiʻi kaʻina. Keia mea no ka mea, o ka maʻiʻo ma kekahi tonne o ka pōhaku, aole ia i oi aku mamua o 24 nā huna. Eia kekahi, o ka hehee ai ma muli o ke 'ano like Nine Inch waiwai i loa paʻakikī eʻike mai ka tantalum.

Ma lalo o maoli kumu i loaʻa ma ka hoopuehu aku ana ano wale - ma igneous pōhaku a me nā pōaka, e like me kekahi hapa o kekahi mau nā minelala hao - pyrochlore loparite, columbite-tantalite. Kēia hehee ai o ka papa'āweʻaweʻa kemika'ōnaehana ua extractedʻano nui mai ka makana i huiʻia. niobium? iecaianoaaiiuo ninoieo o ekolu kahua o ka hoʻonaʻauao.

1. Autopsy pōhaku me ka maʻiʻo kiʻekiʻe o niobium mea.
2. Branch o niobium tantalum, hoʻomākaukau maemae i huiʻia.
3. Ke ola a me ka hoomaemae ana o ka metala a me kona oka a mai impurities.

Ke kumu o ka? Iecaianoaaiiie kalapona i kiʻekiʻe-wela thermal keʻano o ka hanaʻana hoʻohana Aluminum, paʻakai 'ole kalapona. Koke wehe niobium pauka hoomakaukauia ma ka ua e, sintering o ka pauka "polū" ma ka vacuo, a me ka huina'ine-ulana lole piʻo heheʻe.

maikaʻi kēia waiwai

Manawa i kona ano poʻokela o ka niobium ua hoʻohana 'ia i loko o na mea he nui na hana. E kōkua i ka hoʻokō 'ana o ke kumu o hehee ai i loko o ka haku mele' ana haʻilula, i na ua olokaaiaʻe huahana, me niobium loloa. I ka papa kuhikuhiEʻeleu 'Oponopono ma keia hihia ka niobium carbide, i loaʻa he pono ia ma luna o ka ÿano waiwai o ka mea. No ka doping no ke tona o ke kila pono wale 200 nā huna o ka niobium. Ke kūpono oka a ua kiʻekiʻe paakiki a me ka ductility, haahaa friability, maikaʻi ka popopo e kū'ē'ē mai. Ke hehee ai hoʻohana no ka aiiay a me ka 'ole-ferrous ke hooheheeia, pakahi aku la ia Aluminum, mai alkalis a me nāʻakika.

Ka hoʻohana o niobium

Niobium e hoomaemae ia ua ka hapanui hoʻohana like me ka dopant e ho okumu i nā oka a mai ferrous a me ka ferrous ke hooheheeia. I ka papa kuhikuhiE palapala noi i niobium rocket, Radio a me ka lolouila ka hana 'enekinia, Nine Inch i hoʻomākaukauʻia kūkuluʻia, a me ka aeronautical astronautical wilikî.

Noi o ka mea hao a maʻemaʻe niobium no a hiki i ka helu o kona pono waiwai. Iwaena o lakou o ka Naauao refractoriness, ia'ku i ka popopo, waiwai, e hoʻomāhuahua i ka wela ia'ku o nā mea a me kā lākou lawelawe nona iho.

Unique quality, a i ka niobium e hoomaemae ia mea kokoke Aʻohe AaOIeIOUIeXAOAaIN kālaiōewe o ka uranium i ka wela o ka i a hiki i 1100 kekelē Kelekia. A, i ka'Ātoma he haʻahaʻaʻimi hoʻopunipuni radioactivity. A pau keia hana ka mea pono no ka hoomalu ana i nukelea reactors, e like me ipu no ka papaa o ka pau keia la radioactive wahie.

? Iecaianoaaiiuo o niobium

O ka niobium metala huahana meaʻano nui e hālāwai me ka pono o ka nukelea hana. Aiaʻili lahilahi hoomakaukau mea no ka uranium a me ka plutonium teplovyvodyaschih hehee wale, ipu no ka ho'āhu wai a ke hooheheeia, radioactive neoneo. Products i ka niobium hoʻohana i ka hana kaumaha hana Me. Me ia, hoemi i ka ia'ku o na conductors, malaila loaa cryotrons - sverhvysokoprovodyaschie kamepiula hehee wale. Ma Austria, ke kālā, a me ka niobium oka a hoʻohana no ka minting o nâ malihini ÿauhau.
