Kodi lanthanum carbonate amagwiritsidwa ntchito bwanji?

Mapangidwe a lanthanum carbonate

Lanthanum carbonatendi mankhwala ofunikira opangidwa ndilanthanum, carbon, ndi zinthu za oxygen. Njira yake yamankhwala ndi La2 (CO3) 3, pomwe La imayimira lanthanum element ndipo CO3 imayimira carbonate ion.Lanthanum carbonatendi woyera crystalline olimba ndi wabwino matenthedwe ndi mankhwala bata.

Pali njira zingapo zopangira lanthanum carbonate.Njira wamba ndikuchitapo kanthulanthanum zitsulondi kuchepetsa nitric asidi kupeza lanthanum nitrate, amene kenako anachita ndi sodium carbonate kupangalanthanum carbonatemvula. Kuphatikiza apo,lanthanum carbonateItha kupezekanso pochita sodium carbonate ndi lanthanum chloride.

Lanthanum carbonate ili ndi ntchito zosiyanasiyana zofunika.Choyamba,lanthanum carbonateangagwiritsidwe ntchito ngati zofunika zopangira lanthanide zitsulo.Lanthanumndi aRare earth metalokhala ndi maginito ofunikira, owoneka bwino, ndi ma electrochemical, omwe amagwiritsidwa ntchito kwambiri m'magawo monga zamagetsi, optoelectronics, catalysis, ndi zitsulo.Lanthanum carbonate, monga kalambulabwalo wofunika wa zitsulo lanthanide, akhoza kupereka mfundo zofunika ntchito m'madera amenewa.

Lanthanum carbonateangagwiritsidwenso ntchito pokonzekera mankhwala ena. Mwachitsanzo, kuchitapo kanthulanthanum carbonatendi asidi sulfuric kubala lanthanum sulphate angagwiritsidwe ntchito pokonzekera chothandizira, zipangizo batire, etc.lanthanum carbonatendi ammonium nitrate amapanga ammonium nitratelanthanum, omwe angagwiritsidwe ntchito pokonzekera lanthanide zitsulo oxides,lanthanum oxide, ndi zina.

Lanthanum carbonateilinso ndi mtengo wina wake wamankhwala. Kafukufuku wasonyeza kutilanthanum carbonateAngagwiritsidwe ntchito pochiza hyperphosphatemia. Hyperphosphatemia ndi matenda a impso, omwe nthawi zambiri amatsagana ndi kuchuluka kwa phosphorous m'magazi.Lanthanum carbonateakhoza kuphatikiza ndi phosphorous mu chakudya kupanga insoluble zinthu, potero kuchepetsa mayamwidwe phosphorous ndi ndende ya phosphorous m'magazi, kusewera achire udindo.

Lanthanum carbonateAngagwiritsidwenso ntchito pokonzekera zipangizo za ceramic. Chifukwa cha kukhazikika kwake kwamafuta ndi mankhwala,lanthanum carbonateamatha kulimbitsa mphamvu, kuuma, ndi kuvala kukana kwa zida za ceramic. Chifukwa chake, mumakampani a ceramic.lanthanum carbonateNthawi zambiri amagwiritsidwa ntchito pokonzekera zinthu monga zitsulo zotentha kwambiri, zoumba zamagetsi, zoumba zowoneka bwino, etc.

Lanthanum carbonateangagwiritsidwenso ntchito kuteteza chilengedwe. Chifukwa cha kutsatsa kwake komanso ntchito zake zochititsa chidwi,lanthanum carbonateangagwiritsidwe ntchito mu matekinoloje osamalira zachilengedwe monga kuthira madzi onyansa komanso kuyeretsa gasi. Mwachitsanzo, mwa kuchitapo kanthulanthanum carbonatendi ayoni olemera kwambiri m'madzi otayira kuti apange ma insuluble precipitates, cholinga chochotsa zitsulo zolemera chimakwaniritsidwa.

Lanthanum carbonatendi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito kwambiri. Sizofunika zokha zopangira zitsulo za lanthanide, komanso zingagwiritsidwe ntchito pokonzekera mankhwala ena, mankhwala a hyperphosphatemia, kukonzekera zipangizo za ceramic, ndi kuteteza chilengedwe. Ndi chitukuko mosalekeza sayansi ndi luso, ntchito ziyembekezo zalanthanum carbonateidzakhala yotakata.
