Mbiri ndi Zochitika Zonse
Zosowa zapadziko lapansindi floorboard IIIB scandium, yttrium ndi lanthanum mu periodic tebulo.Pali zinthu l7.Dziko losowa lili ndi zinthu zapadera komanso zamankhwala ndipo lakhala likugwiritsidwa ntchito kwambiri m'makampani, ulimi ndi madera ena.Chiyero cha zinthu zosawerengeka zapadziko lapansi zimatsimikizira mwachindunji zinthu zapadera za zipangizozo.Kuyeretsedwa kosiyana kwa zinthu zapadziko lapansi zosowa kumatha kupanga zida za ceramic, zida za fulorosenti ndi zida zamagetsi zomwe zimakhala ndi zofunikira zosiyanasiyana.Pakalipano, ndi chitukuko cha luso lazofukula zapadziko lapansi, zinthu zoyera zapadziko lapansi zosadziwika bwino zimapereka chiyembekezo chabwino cha msika, ndipo kukonzekera kwa zipangizo zapadziko lapansi zomwe zimagwira ntchito kwambiri kumapangitsa kuti pakhale zofunikira zapamwamba zapadziko lapansi zosadziwika bwino.Cerium pawiri ali ndi ntchito zosiyanasiyana, ndipo zotsatira zake mu ntchito zambiri zimagwirizana ndi chiyero chake, katundu wakuthupi ndi zonyansa.Pakugawidwa kwa zinthu zosowa padziko lapansi, cerium imapanga pafupifupi 50% ya zinthu zapadziko lapansi.Pakuchulukirachulukira kwa cerium yoyera kwambiri, kufunikira kwa index yapadziko lapansi yomwe siili yosowa kwambiri pamitundu ya cerium ndiyokwera kwambiri.Cerium oxidendi ceric oxide, nambala ya CAS ndi 1306-38-3, ndondomeko ya maselo ndi CeO2, kulemera kwa maselo: 172.11;Cerium oxide ndiye oxide wokhazikika kwambiri wa rare Earth element cerium.Ndi yotumbululuka yachikasu yolimba pa kutentha kwa chipinda ndipo imakhala yakuda ikatenthedwa.Cerium oxide imagwiritsidwa ntchito kwambiri muzinthu zowunikira, zopangira, ufa wopukutira, zotchinga za UV ndi zinthu zina chifukwa chakuchita bwino.M’zaka zaposachedwapa, zachititsa chidwi ofufuza ambiri.Kukonzekera ndi kuchita kwa cerium oxide kwakhala malo opangira kafukufuku m'zaka zaposachedwa.
Njira Yopanga
Njira 1: Yambitsani kutentha kwa chipinda, onjezerani sodium hydroxide solution ya 5.0mol/L ku cerium sulfate solution ya 0.1mol/L, sinthani pH kuti ikhale yayikulu kuposa 10, ndipo mvula imachitika.Dothilo limapopedwa, kutsukidwa kangapo ndi madzi oyeretsedwa, kenaka kuyanika mu uvuni wa 90 ℃ kwa maola 24.Pambuyo popera ndi kusefa (tinthu kukula zosakwana 0.1mm), cerium okusayidi analandira ndi kuikidwa pa malo ouma kuti losindikizidwa yosungirako.Njira 2: Kutenga cerium chloride kapena cerium nitrate ngati zopangira, kusintha pH kukhala 2 ndi madzi ammonia, kuwonjezera oxalate kuti ipangitse cerium oxalate, mutatha kutentha, kuchiritsa, kupatukana ndi kuchapa, kuyanika pa 110 ℃, kenako kuyaka ku cerium oxide pa 900. ~ 1000 ℃.Cerium oxide imatha kupezeka potenthetsa chisakanizo cha cerium oxide ndi carbon powder pa 1250 ℃ mumlengalenga wa carbon monoxide.
Kugwiritsa ntchito
Cerium Oxide ntchito zina za makampani galasi, mbale galasi akupera zipangizo, ndipo wakhala anawonjezera kwa magalasi akupera galasi, kuwala magalasi, kinescope, bleaching, kumveka, galasi cheza ultraviolet ndi mayamwidwe wa waya zamagetsi, ndi zina zotero.Amagwiritsidwanso ntchito ngati anti-reflector ya mandala agalasi, ndipo cerium amagwiritsidwa ntchito kupanga cerium titaniyamu wachikasu kuti galasi likhale lachikasu.Kutsogolo kwaoxidation yapadziko lapansi kosowa kumakhala ndi chikoka pa crystallization ndi katundu wa zoumba zamagalasi mu dongosolo la CaO-MgO-AI2O3-SiO2.Zotsatira zafukufuku zikuwonetsa kuti kuwonjezera kutsogolo koyenera kwa okosijeni ndikopindulitsa kuwongolera kumveka kwamadzi agalasi, kuthetsa thovu, kupanga kapangidwe kagalasi kukhala kophatikizana, ndikuwongolera magwiridwe antchito amakina ndi kukana kwa zinthu zamchere.Kuchulukitsa kokwanira kwa cerium oxide ndi 1.5, ikagwiritsidwa ntchito mu ceramic glaze ndi mafakitale amagetsi ngati piezoelectric ceramic penetrant.Amagwiritsidwanso ntchito popanga chothandizira kwambiri, chivundikiro cha nyali ya gasi, chophimba cha X-ray fulorosenti (makamaka yogwiritsidwa ntchito popukutira magalasi).Ufa wosawerengeka wa cerium wopukuta umagwiritsidwa ntchito kwambiri mu makamera, magalasi a kamera, chubu la zithunzi za TELEVISION, lens, ndi zina zotero.Itha kugwiritsidwanso ntchito mumakampani opanga magalasi.Cerium oxide ndi titaniyamu woipa angagwiritsidwe ntchito pamodzi kupanga galasi lachikasu.Cerium oxide ya galasi decolorization ili ndi ubwino wokhazikika pa kutentha kwakukulu, mtengo wotsika komanso kusayamwa kwa kuwala kowonekera.Kuonjezera apo, cerium oxide amawonjezeredwa ku galasi logwiritsidwa ntchito m'nyumba ndi magalimoto kuti achepetse kufalikira kwa kuwala kwa ultraviolet.Popanga zida zowala zapadziko lapansi, cerium oxide imawonjezedwa ngati activator mumitundu yosowa yamitundu itatu yamtundu wa phosphors yomwe imagwiritsidwa ntchito muzinthu zowunikira za nyali zopulumutsa mphamvu ndi ma phosphors omwe amagwiritsidwa ntchito powonetsa ndi zowunikira ma radiation.Cerium okusayidi ndi zopangira pokonzekera zitsulo cerium.Kuphatikiza apo, mu zida za semiconductor, ma pigment apamwamba kwambiri komanso zowunikira magalasi owoneka bwino, zoyezera zotulutsa zamagalimoto zakhala zikugwiritsidwa ntchito kwambiri.Chothandizira kuyeretsa utsi wagalimoto makamaka chimapangidwa ndi chonyamulira cha zisa za ceramic (kapena zitsulo) ndi zokutira zoyatsidwa pamwamba.Chophimbacho chimakhala ndi gawo lalikulu la gamma-trioxide, kuchuluka koyenera kwa ma oxides omwe amakhazikika pamtunda, ndi chitsulo chokhala ndi chothandizira chomwazika mkati mwa zokutira.Pofuna kuchepetsa mtengo wa Pt, Rh mlingo, kuonjezera mlingo wa Pd ndi wotsika mtengo, kuchepetsa mtengo wa chothandizira popanda kuchepetsa zopangira zoyeretsera galimoto chifukwa cha ntchito zosiyanasiyana, zomwe zimagwiritsidwa ntchito nthawi zambiri Pt.Pd.Kutsegula kwa Rh ternary catalyst №, nthawi zambiri njira yomiza yokwanira kuonjezera kuchuluka kwa cerium okusayidi ndi lanthanum oxide, kumapangitsa kuti dziko lapansi likhale losowa kwambiri.Chuma chamtengo wapatali chothandizira ternary.Lanthanum oxide ndi cerium oxide adagwiritsidwa ntchito ngati othandizira kuti apititse patsogolo magwiridwe antchito a ¦ A-Alumina adathandizira zopangira zitsulo zabwino kwambiri.Malinga ndi kafukufuku, chothandizira limagwirira wa cerium okusayidi ndi okusayidi lanthanum makamaka kusintha chothandizira ❖ kuyanika yogwira, basi kusintha chiŵerengero mpweya mafuta ndi catalysis, ndi kusintha bata matenthedwe ndi makina mphamvu chonyamulira.
