Kukonzekera njira ndi ntchito mkulu chiyero mkuwa

High chiyero mkuwaamatanthauza chiyero cha mkuwa chimafika 99.999% kapena kupitirira 99.9999%, ndipo katundu wake wosiyanasiyana wakuthupi amakula kwambiri kuposa omwe ali ndi chiyero chochepa.Mkuwa uli ndi mphamvu yabwino yamagetsi ndi matenthedwe, ndipo ndi wosungulumwa komanso wosasunthika.Mkuwa umagwiritsidwa ntchito kwambiri popanga mawaya ndi machubu, koma amathanso kukanikizidwa, kukokedwa, ndikuponyedwa muzinthu zosiyanasiyana.M'zaka zaposachedwa, mkuwa woyeretsedwa kwambiri wakhala ukugwiritsidwa ntchito kwambiri komanso wofunika kwambiri.

Ngati mkuwa woyeretsedwa kwambiri udzagwiritsidwa ntchito ku dera lophatikizika la zida zomvera, kupanga zingwe zomvera, zidzasintha kwambiri kukhulupirika kwa mawu;Mawaya omangira golide omwe amagwiritsidwa ntchito popanga semiconductors amathanso kusinthidwa ndi mkuwa, zomwe zimapulumutsa ndalama.Mkuwa woyeretsedwa kwambiri umakhala ndi kutentha kochepa kofewa, ductility wabwino, ndipo ukhoza kukokedwa mosavuta mu waya woonda.Kugwiritsiridwa ntchito kwa mkuwa woyeretsedwa kwambiri kungapangitse ubwino wa zinthu zamagetsi ndi kuchepetsa mtengo wopangira.

Ukadaulo woyeretsera mkuwa woyengedwa kwambiri unayambika kalekale.Mu 1941, Smart Jr ndi ena anachita kafukufuku pa electrolytic kuyenga, kwambiri kuyeretsa electrolyte, ndipo anachita angapo electrolysis pamodzi ndi mkuwa sulfate njira ndi mkuwa nitrate njira.Mankhwala.Kuyambira pakati pa zaka za m'ma 1950, njira yoyeretsera zitsulo ndi zone kusungunuka inawonekera, ndipo nthawi yomweyo idagwiritsidwa ntchito kuyeretsa mkuwa.Mwa njira iyi, teknoloji yoyeretsa kwambiri yamkuwa inapangidwanso.M'zaka zaposachedwapa, njira yoyeretsera mkuwa pogwiritsa ntchito kusinthana kwa ion yawonekera, ndipo zotsatira zabwino zapezeka.Kukula kwa ukadaulo wamakono kwapitilizabe kukulitsa zofunikira pazinthu zakuthupi.Mkuwa woyeretsedwa kwambiri uli ndi zinthu zambiri zabwino kwambiri, zomwe zingathe kukwaniritsa zofunikira zamakono zamakono zamakono.Zofunikira zaukadaulo, ndipo zakhala zikugwiritsidwa ntchito pazinthu zambiri, ndipo zapeza zotsatira zabwino.
