Kuumbwa kwe lanthanum carbonate
Lanthanum carbonatechinhu chakakosha chemakemikari chinoumbwa nelanthanum, carbon, uye oxygen elements. Mushonga wayo wemakemikari ndeye La2 (CO3) 3, apo La inomiririra lanthanum element uye CO3 inomiririra carbonate ion.Lanthanum carbonateis white crystalline yakasimba ine yakanaka yekupisa uye kugadzikana kwemakemikari.
Kune nzira dzakasiyana dzekugadzira lanthanum carbonate.Nzira yakajairika ndeyekuitalanthanum simbine dilute nitric acid kuti iwane lanthanum nitrate, iyo inobva yaitwa ne sodium carbonate kuumbalanthanum carbonateprecipitate. Pamusoro pe,lanthanum carbonateinogonawo kuwanikwa nekuita sodium carbonate ne lanthanum chloride.
Lanthanum carbonate ine akasiyana akakosha maapplication.Chekutanga,lanthanum carbonateinogona kushandiswa sechinhu chakakosha mbishi ye lanthanide simbi.Lanthanumari arare earth metaline zvakakosha magineti, optical, uye electrochemical zvimiro, zvinoshandiswa zvakanyanya muminda senge zvemagetsi, optoelectronics, catalysis, uye simbi.Lanthanum carbonate, seyakakosha precursor ye lanthanide simbi, inogona kupa yakakosha zvinhu zvekushandisa muminda iyi.
Lanthanum carbonateinogonawo kushandiswa kugadzira mamwe makomisheni. Somuenzaniso, kuitalanthanum carbonatene sulfuric acid kugadzira lanthanum sulfate inogona kushandiswa kugadzira catalysts, bhatiri zvinhu, nezvimwe.lanthanum carbonateneammonium nitrate inogadzira ammonium nitrate yelanthanum, iyo inogona kushandiswa kugadzira lanthanide simbi oxides,lanthanum oxide, nezvimwewo.
Lanthanum carbonateinewo imwe kukosha kwekushandisa kwekurapa. Tsvakurudzo yakaratidza izvozvolanthanum carbonateInogona kushandiswa kurapa hyperphosphatemia. Hyperphosphatemia chirwere cheitsvo, chinowanzoperekedzwa nekuwedzera kwemazinga e phosphorus muropa.Lanthanum carbonateinogona kusanganisa ne phosphorus muzvokudya kuti igadzire zvinhu zvisinganyunguriki, nokudaro kuderedza kutorwa kwe phosphorus uye kuwanda kwe phosphorus muropa, kutamba basa rekurapa.
Lanthanum carbonateinogonawo kushandiswa kugadzira ceramic zvinhu. Nekuda kwekunaka kwayo kupisa uye kugadzikana kwemakemikari,lanthanum carbonateinogona kuvandudza kusimba, kuoma, uye kupfeka kuramba kweceramic zvinhu. Naizvozvo, muindasitiri yeceramic,lanthanum carbonateinowanzo shandiswa kugadzira zvinhu zvakadai semakeramiki epamusoro-tembiricha, makeramiki emagetsi, optical ceramics, nezvimwe.
Lanthanum carbonateinogona kushandiswawo kuchengetedza zvakatipoteredza. Nekuda kweiyo adsorption kugona uye catalytic chiitiko,lanthanum carbonateinogona kushandiswa mumatekinoroji ekurapa kwezvakatipoteredza senge kurapwa kwemvura yetsvina uye exhaust gasi kucheneswa. Somuenzaniso, nokuitalanthanum carbonateneheavy metal ions mumvura yetsvina kuti iite insoluble precipitates, chinangwa chekubvisa masimbi anorema chinowanikwa.
Lanthanum carbonatechinhu chakakosha chemakemikari chine hukuru hwekushandisa. Haisi chete yakakosha mbishi zvinhu zve lanthanide simbi, asi inogona zvakare kushandiswa mukugadzirira kwemamwe makomisheni, kurapwa kwe hyperphosphatemia, kugadzirwa kweceramic zvinhu, uye kuchengetedzwa kwezvakatipoteredza. Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, tarisiro yekushandisa yelanthanum carbonateichawedzera.
