Yiziphi ukusetshenziswa kwe-lanthanum carbonate?

Ukwakhiwa kwe-lanthanum carbonate

I-Lanthanum carbonateiyikhemikhali ebalulekile eyakhiwei-lanthanum, ikhabhoni, nezakhi zomoya-mpilo. Ifomula yayo yamakhemikhali i-La2 (CO3) 3, lapho i-La imele i-lanthanum element futhi i-CO3 imele i-carbonate ion.I-Lanthanum carbonateiyikristale emhlophe eqinile enokuqina okuhle kokushisayo namakhemikhali.

Kunezindlela ezahlukahlukene zokulungiselela i-lanthanum carbonate.Indlela evamile ukusabelainsimbi ye-lanthanumnge-dilute nitric acid ukuze uthole i-lanthanum nitrate, esabela nge-sodium carbonate ukuze yakhekei-lanthanum carbonateimvula. Ngaphezu kwalokho,i-lanthanum carbonateingatholakala futhi ngokuphendula i-sodium carbonate ne-lanthanum chloride.

I-Lanthanum carbonate inezinhlelo zokusebenza ezihlukahlukene ezibalulekile.Okokuqala,i-lanthanum carbonateingasetshenziswa njengento ebalulekile eluhlaza yezinsimbi ze-lanthanide.I-Lanthanumyin ainsimbi yomhlaba engavamileenezici ezibalulekile zikazibuthe, ezibonakalayo, kanye ne-electrochemical, ezisetshenziswa kakhulu emikhakheni efana ne-electronics, optoelectronics, catalysis, kanye ne-metallurgy.I-Lanthanum carbonate, njengesandulela esibalulekile sezinsimbi ze-lanthanide, ingahlinzeka ngezinto eziyisisekelo zokusetshenziswa kule mikhakha.

I-Lanthanum carbonateingasetshenziswa futhi ukulungisa ezinye izinhlanganisela. Ngokwesibonelo, ukusabelai-lanthanum carbonatenge-sulfuric acid ukukhiqiza i-lanthanum sulfate ingasetshenziswa ukulungisa ama-catalysts, izinto zebhethri, njll.i-lanthanum carbonatenge-ammonium nitrate ikhiqiza i-ammonium nitratei-lanthanum, engasetshenziswa ukulungisa i-lanthanide metal oxides,i-lanthanum oxide, njll.

I-Lanthanum carbonatefuthi inenani elithile lesicelo somuthi. Ucwaningo luye lwabonisa lokhoi-lanthanum carbonateIsetshenziselwa ukwelapha i-hyperphosphatemia. I-Hyperphosphatemia yisifo sezinso esivamile, esivame ukuhambisana nokwanda kwamazinga e-phosphorus egazini.I-Lanthanum carbonateingahlangana ne-phosphorus ekudleni ukwenza izinto ezingancibiliki, ngaleyo ndlela inciphise ukumuncwa kwe-phosphorus kanye nokugcwala kwe-phosphorus egazini, idlala indima yokwelapha.

I-Lanthanum carbonateingasetshenziswa futhi ukulungisa izinto ze-ceramic. Ngenxa yokuqina kwayo okushisayo namakhemikhali,i-lanthanum carbonateingathuthukisa amandla, ubulukhuni, nokumelana nokugqoka kwezinto ze-ceramic. Ngakho-ke, embonini ye-ceramic,i-lanthanum carbonatekuvame ukusetshenziselwa ukulungisa izinto ezifana nezitsha zobumba ezisezingeni eliphezulu, izitsha zobumba ze-elekthronikhi, i-optical ceramics, njll.

I-Lanthanum carbonateingasetshenziselwa futhi ukuvikela imvelo. Ngenxa yomthamo wayo we-adsorption kanye nomsebenzi we-catalytic,i-lanthanum carbonateingasetshenziswa kubuchwepheshe bokwelashwa kwemvelo njengokwelashwa kwamanzi angcolile kanye nokuhlanzwa kwegesi ephumayo. Ngokwesibonelo, ngokusabelai-lanthanum carbonatengama-ion ensimbi esindayo emanzini angcolile ukuze enze ama-insoluble precipitates, umgomo wokukhipha izinsimbi ezinzima uyafinyelelwa.

I-Lanthanum carbonateiyikhemikhali ebalulekile enenani elikhulu lokusetshenziswa. Akuyona nje into ebalulekile yokusetshenziswa kwezinsimbi ze-lanthanide, kodwa futhi ingasetshenziswa ekulungiseleleni ezinye izinhlanganisela, ukwelashwa kwe-hyperphosphatemia, ukulungiswa kwezinto zobumba, nokuvikelwa kwemvelo. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, amathemba okusebenza wei-lanthanum carbonateizoba banzi nakakhulu.
