Le tuufaatasiga o le lanthanum carbonate
Lanthanum carbonateose vaila'au taua e fausia ailanthanum, kaponi, ma elemene okesene. O lona fua fa'atatau o le La2 (CO3) 3, lea o lo'o fa'atusalia e La le elemene lanthanum ma o le CO3 o lo'o fa'atusalia ai le ion carbonate.Lanthanum carbonateo se tioata pa'epa'e mautu ma mautu lelei vevela ma vailaau.
E i ai auala eseese mo le saunia o le lanthanum carbonate.O le auala masani o le tali atuuamea lanthanumfa'atasi ai ma le nitric acid fa'afefete ina ia maua ai le lanthanum nitrate, ona fa'afo'i lea ma le sodium carbonate e fai ailanthanum carbonatemalele. I le male,lanthanum carbonatee mafai foi ona maua e ala i le taliina o le sodium carbonate ma le lanthanum chloride.
Lanthanum carbonate e tele fa'aoga taua.Muamua,lanthanum carbonatee mafai ona faʻaaogaina e fai ma mea taua mo metala lanthanide.Lanthanumo le au'amea eleele e seaseafa'atasi ai ma mea taua fa'amaneta, opitika, ma eletise, fa'aaogaina lautele i matā'upu e pei o mea tau eletise, optoelectronics, catalysis, ma metallurgy.Lanthanum carbonate, e avea o se mea taua o metala lanthanide, e mafai ona maua ai se mea taua mo talosaga i nei fanua.
Lanthanum carbonatee mafai fo'i ona fa'aoga e saunia ai isi mea fa'afefiloi. Mo se faataitaiga, tali atulanthanum carbonatefa'atasi ai ma le sulfuric acid e maua mai ai le lanthanum sulfate e mafai ona fa'aoga e saunia ai fa'amalosi, mea maa, ma isi.lanthanum carbonatema le ammonium nitrate e maua ai le ammonium nitrate olanthanum, lea e mafai ona faʻaaogaina e saunia ai lanthanide metal oxides,lanthanum oxide, ma isi.
Lanthanum carbonateo lo'o iai fo'i ni aogā fa'apitoa mo togafitiga. O suʻesuʻega ua faʻaalia ai lena mealanthanum carbonatee mafai ona faʻaaogaina e togafitia ai le hyperphosphatemia. O le Hyperphosphatemia o se fa'ama'i fatuga'o masani, e masani ona fa'atasi ma le fa'ateleina o le maualuga o le phosphorus i le toto.Lanthanum carbonatee mafai ona tuʻufaʻatasia ma le phosphorus i meaʻai e fausia ai mea e le mafai ona faʻaaogaina, ma faʻaitiitia ai le faʻaogaina o le phosphorus ma le faʻaogaina o le phosphorus i totonu o le toto, o loʻo taʻalo ai se vaega togafitiga.
Lanthanum carbonatee mafai fo'i ona fa'aoga e saunia ai mea fa'amea. Ona o lona tulaga sili ona lelei le mafanafana ma le kemisi,lanthanum carbonatee mafai ona faʻaleleia le malosi, maʻaʻa, ma le faʻaogaina o mea faʻameamea. O le mea lea, i le alamanuia keramika,lanthanum carbonatee masani ona faʻaaogaina e saunia ai mea e pei o ceramics maualuga-vevela, ceramics eletise, ceramics optical, etc.
Lanthanum carbonatee mafai foi ona faaaoga mo le puipuiga o le siosiomaga. Ona o lona gafatia adsorption ma catalytic gaioiga,lanthanum carbonatee mafai ona faʻaaogaina i tekonolosi togafitiga faʻalesiosiomaga e pei o le faʻamamaina o le suavai otaota ma le faʻamamaina o kesi. Mo se faataitaiga, e ala i le tali atulanthanum carbonatefa'atasi ai ma ion u'amea mamafa i vai fa'aleaga e fa'atupu ai ni fa'aputuga e le mafai ona solu, ua ausia le sini o le aveeseina o u'amea mamafa.
Lanthanum carbonateose vaila'au taua e tele lona aoga. E le gata o se mea mataʻutia taua mo metala lanthanide, ae mafai foi ona faʻaaogaina i le sauniuniga o isi mea faʻapipiʻi, togafitiga o le hyperphosphatemia, sauniuniga o mea sima, ma le puipuiga o le siosiomaga. Faatasi ai ma le faʻaauauina o le atinaʻeina o saienisi ma tekinolosi, o le faʻamoemoega o talosaga olanthanum carbonateo le a sili atu ona lautele.
