Ukuqulunqwa kwe-lanthanum carbonate
ILanthanum carbonateYikhemikhali ebalulekileyo eyenziwe ngayolanthanum, ikharbhon, kunye neoksijini.Indlela yayo yeekhemikhali yiLa2 (CO3) 3, apho iLa imele i-lanthanum element kunye ne-CO3 imele i-carbonate ion.ILanthanum carbonateyikristale emhlophe eqinileyo enozinzo oluhle lwe-thermal kunye neekhemikhali.
Kukho iindlela ezahlukeneyo zokulungiselela i-lanthanum carbonate.Indlela eqhelekileyo kukusabelaintsimbi ye-lanthanumkunye ne-dilute nitric acid ukufumana i-lanthanum nitrate, ethi ke iphendule nge-sodium carbonate ukwenzalanthanum carbonateimvula.Ukwengeza,lanthanum carbonateinokufumaneka kwakhona ngokusabela i-sodium carbonate kunye ne-lanthanum chloride.
ILanthanum carbonate inezicelo ezahlukeneyo ezibalulekileyo.Okokuqala,lanthanum carbonateingasetyenziswa njengento ebalulekileyo ekrwada kwiintsimbi ze-lanthanide.Lanthanumyiintsimbi yomhlaba enqabileyokunye neempawu ezibalulekileyo zemagneti, zamehlo, kunye ne-electrochemical, esetyenziswa ngokubanzi kwimimandla efana ne-elektroniki, i-optoelectronics, i-catalysis, kunye ne-metallurgy.ILanthanum carbonate, njenge-precursor ebalulekileyo ye-lanthanide metals, inokubonelela ngezinto ezisisiseko kwizicelo kule mimandla.
ILanthanum carbonateingasetyenziselwa ukulungisa ezinye iikhompawundi.Umzekelo, ukusabelalanthanum carbonatenge sulphuric acid ukuvelisa i-lanthanum sulfate ingasetyenziselwa ukulungisa izinto ezibangela ukuba kubekho i-catalysts, izinto zebhetri, njl. njl.lanthanum carbonatenge ammonium nitrate ivelisa ammonium nitratelanthanum, enokusetyenziswa ukulungisa i-lanthanide metal oxides,i-lanthanum oxide, njl.
ILanthanum carbonateKananjalo inexabiso elithile lesicelo sonyango.Uphando luye lwabonisa ukubalanthanum carbonateingasetyenziselwa ukunyanga i-hyperphosphatemia.I-Hyperphosphatemia sisifo sezintso esiqhelekileyo, esihlala sihamba kunye nokunyuka kwamanqanaba e-phosphorus egazini.ILanthanum carbonateinokudibanisa ne-phosphorus ekutyeni ukwenza izinto ezinganyibilikiyo, ngaloo ndlela inciphisa ukufunxwa kwe-phosphorus kunye nokuxinana kwe-phosphorus egazini, idlala indima yonyango.
ILanthanum carbonateingasetyenziselwa ukulungisa izinto ze-ceramic.Ngenxa yozinzo olugqwesileyo lwe-thermal kunye neekhemikhali,lanthanum carbonateinokuphucula amandla, ukuqina, kunye nokunxiba ukuxhathisa kwezixhobo ze-ceramic.Ke ngoko, kwishishini le-ceramic.lanthanum carbonateihlala isetyenziselwa ukulungiselela izinto ezifana neekeramics zobushushu obuphezulu, iiseramikhi zombane, iiseramics zokukhanya, njl.
ILanthanum carbonateingasetyenziselwa ukhuseleko lokusingqongileyo.Ngenxa yomthamo wayo we-adsorption kunye nomsebenzi we-catalytic,lanthanum carbonateinokusetyenziswa kubuchwephesha bonyango lokusingqongileyo njengonyango lwamanzi amdaka kunye nokucocwa kwegesi yokukhupha.Ngokomzekelo, ngokusabelalanthanum carbonatekunye ion zetsimbi enzima emanzini amdaka ukwenza i-insoluble precipitates, injongo yokususa isinyithi esinzima sifezekiswa.
ILanthanum carbonateyinto ebalulekileyo yekhemikhali enexabiso elikhulu lokusetyenziswa.Akuyona nje into ebalulekileyo ekrwada yesinyithi se-lanthanide, kodwa ingasetyenziselwa ukulungiswa kwezinye iikhompawundi, unyango lwe-hyperphosphatemia, ukulungiswa kwezinto ze-ceramic, kunye nokukhuselwa kwendalo.Ngophuhliso oluqhubekayo lwesayensi kunye nobuchwepheshe, amathuba okusetyenziswa kwelanthanum carbonateiya kuba banzi ngakumbi.
