Intshayelelo Eneenkcukacha
I-lanthanumInqaku lekhemikhali kunye nenombolo ye-le okanye inombolo yeatomic 57. Yenzelwe iqela lezinto ezaziwa ngokuba yi-lanthanides, ezona zixhobo zentsimbi ezili-15 ezikwiikhiloti zexesha elinamaxesha athile phantsi kweentsimbi ze-test.
I-Lanthanum yafunyanwa ekuqaleni ngo-1839 ngeSweden Cheml gust gust sust mosander xa wayesodwa kwi-cerium nitrate. Igama layo livela igama lesiGrike elithi "Lanthanein," elithetha "ukuba lifihlwe" njengoko iLanthanum ihlala ifunyanwa kunye nezinye izinto kwii-minerals ezahlukeneyo.
Kwifom yayo ecocekileyo, i-lanthanum yintsimbi ethambileyo, i-Silly-mhlophe-emhlophe esebenzayo kwaye inyanzelekile ukuba ichukumiseke emoyeni. Yenye yezona zinto zininzi ze-lanthanaide yeziyolo kodwa ziqhelekile kunezinto ezifana negolide okanye iplatinam.
I-Lanthanum ngokuyintloko ifunyanwa kwiiminerals ezinje ngeMonazite kunye neBestnäsite, equlethe umxube wezinto ezinqabileyo zomhlaba.
I-Lanthanum inepropathi eliqela ebonakalayo eyenza ukuba iluncedo kwizicelo ezahlukeneyo. Inomxholo ophezulu wokunyibilikisa kwaye inokumelana nobushushu obuphakamileyo, nto leyo eyenza ilungele ukusetyenziswa kwi-probon ye-arbon ye-arbon ye-ARNAN ye-probon, isibane seStudio, kunye nezinye izicelo ezifuna imithombo yokukhanya. Ikwasetyenziswa kwimveliso ye-Cathode tubes (CRS) ye-TVEVVERS kunye neemonitorars.
Ukongeza, i-lanthanum isetyenziswa kwicandelo le-catalysis, apho inokuphucula umsebenzi weecatalys ezithile ezisetyenzisiweyo ukuphendula kweekhemikhali. Ikwafumene izicelo ekuvelisweni kweebhetri zeHybrid zombane, iilensi zokwenza izinto, kunye ne-insonge kwiglasi kunye nezixhobo ze-ceramic ukuphucula amandla kunye nokuchasana nokucutha.
I-Lanthanum complets isetyenziswa kumayeza. Umzekelo, i-lanthannate carbonate, inokumiselwa njenge-phosphate ye-phosphate ukunceda ukulawula amanqanaba aphezulu e-phosphatele kwigazi lesifo sezintso. Isebenza ngokubopha kwi-phosphate kwitrayiti yokugaya, ukuthintela ukufunxa kwegazi.
Ngokubanzi, i-lanthanum yinto eguquguqukayo kunye noluhlu lwezicelo kumashishini anjengokukhanyisa, i-elektroniki, i-catalysis, iyeza. Iipropathi zayo ezahlukileyo kwaye ziphinde zenze ukuba zibe lixabiseke kwimihlaba eyahlukeneyo yobuchwephesha kunye neyenzululwazi.
Isicelo
I-Lanthanum inezicelo ezininzi kumashishini ahlukeneyo ngenxa yepropathi eyahlukileyo:
Ukukhanya:I-Lanthanum isetyenziselwa ukuveliswa kwe-Carbon Lamps, esetyenziswa kwiiprojeki zefilimu, ukukhanya kwesitudiyo, kunye nezibane. Ezi zibane zivelisa ukukhanya okuqaqambileyo, ezibenza bazilungele izicelo ezifuna ukhanyiso oluphezulu.
I-elektroniki:I-Lanthanum isetyenziswa ekuvelisweni kwe-tubes ye-cathode ray (i-CRS) ye-TVEVVImers kunye neemonitorars. I-CRRS isebenzisa i-Electron ibeam ukwenza imifanekiso kwisikrini, kwaye uLanthanum uqashwe kumpu wezixhobo zezi zixhobo.
Iibhetri:I-Lanthanum isetyenziswa ekwenzeni i-Nydride Hydride (Nimh) iibhetri, eziqhele ukusetyenziswa kwizithuthi zombane zeHybrid (Hevs). I-lanthanum-i-iNcclel alloys yinxalenye ye-electrode engalunganga yebhetri, igalelo kwintsebenzo yalo kunye nomthamo.
I-Optics:I-Lanthanum isetyenziselwa ukuveliswa kweelensi zokukhetha ezikhethekileyo kunye neeglasi. Inokonyusa isalathiso sokuqaqamba kunye neepropathi zokusasaza kwezi zixhobo, zibenza basebenzise izicelo ezinjengeemeyili zekhamera kunye neemfumba.
I-AutoMotive Catalysts:I-Lanthanum isetyenziswa njengeyona nto iphambili kwiinkqubo zokuphelisa izithuthi. Inceda ukuguqula ukukhutshwa okuyingozi, njenge-nitrogen oxides (i-nox), i-carbon monoxide (CO), kunye ne-hydrocarbons (HC), kwizinto ezinokubangela izinto eziyingozi.
Iglasi kunye ne-ceramics:I-lanthanum oxide isetyenziswa njengesongezelelo kwimveliso yeglasi kunye ne-ceramic. Inika ubushushu obufanelekileyo kunye nePhakamisayo ezothusayo, zenza ukuba iimveliso zokugqibela zihlala zihlala zomelele kwaye zingaphantsi komonakalo.
Izicelo zamayeza:I-Lanthanam ye-Lanthanhan, enjengeLanthanum Carbonate, isetyenziswa kumayeza njengee-phosphate ze-phosphate kunyango lwezigulana ezinesifo sezintso esingenasifo. Ezi ntenguws zibopha kwi-phosphate kwitrayiti yokugaya, ukuthintela ukufakwa kwayo kwigazi.
I-MetalArgy: I-Lanthahum inokongezwa kwiziqinisekiso ezithile ukuphucula amandla abo kunye nokuxhathisa kobushushu obuphezulu. Isetyenziselwa ukuveliswa kweentsimbi ezizodwa kunye ne-alloys yezicelo ezinje nge-aerospace kunye neenjini zokusebenza eziphezulu.
Le yimizekelo nje embalwa ye-lanthanum. Ipropathi yayo eyahlukileyo yenza ukuba ixabiseke kumashishini ahlukeneyo, igalelo kwinkqubela phambili kwitekhnoloji, amandla, amabona, kunye nokhathalelo lwempilo.
