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.ILanthanumyiintsimbi yomhlaba enqabileyokunye neempawu ezibalulekileyo zemagneti, zamehlo, kunye ne-electrochemical, ezisetyenziswa 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 sulfuric acid ukuvelisa lanthanum sulfate ingasetyenziselwa ukulungiselela catalysts, izinto zebhetri, 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 kunye ne-phosphorus ekutyeni ukwenza izinto ezinganyibilikiyo, ngaloo ndlela inciphisa ukufunxwa kwe-phosphorus kunye noxinzelelo lwe-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 kokusingqongileyo. Ngophuhliso oluqhubekayo lwesayensi kunye nobuchwepheshe, amathuba okusetyenziswa kwelanthanum carbonateiya kuba banzi ngakumbi.
