M'zaka zaposachedwa, kugwiritsa ntchito kwa Lantanide Regents mu synthesis pynthesis kwachulukitsidwa ndi kudumpha ndi malire. Pakati pawo, zoyeserera zambiri za lantanide zidapezeka kuti zidasankha zoonekeratu kuti apagasi yokhudza kaboni; Nthawi yomweyo, ma rephede ambiri a Lantanide adapezeka kuti ali ndi mikhalidwe yabwino mu ma oxidation organic amasinthana ndi kuchepetsa zomwe zimachitika kuti asinthe magulu. Kugwiritsa ntchito kwaibisali padziko lapansi ndi kusintha kwa sayansi ndi zochitika zaku China zomwe zimapezeka ndi antchito asayansi aku China patatha zaka zambiri pantchito yovuta, ndipo yakhala yolimbikitsidwa chifukwa chowonjezera chaulimi ku China. RARE DRORTOTION imasungunuka mosavuta mu asidi kuti apange mchere wambiri ndi kaboni dayokisi, yomwe imatha kugwiritsidwa ntchito mosavuta mu kapangidwe kake ndi zovuta zomwe zimapangitsa kuti zisakhale zonyansa. Mwachitsanzo, imatha kuchitira ndi ma acid amphamvu monga nitric acid, hydrochloric acid, nitric acid, pericloric acid, ndi sulfuric acid, ndi sulufuric acid kukhala mchere. Chitani ndi phosphoric acid ndi hydrofluoric acid kusinthitsa kukhala zopanda pake zachilengedwe ndi fluorides. Chitani zinthu zambiri zomwe anthu ambiri amapanga zofananira zapadziko lapansi. Amatha kukhala osungunuka pakati kapena anions ovutikira, kapenanso osalowerera ndale amaletsedwa kutengera mtengo wake. Kumbali ina, nyama ya carbonate ya carbonate imatha kuwonongeka m'magulu ofanana, omwe amatha kugwiritsidwa ntchito mwachindunji pokonzekera zida zapadziko lapansi zatsopano. Pakadali pano, mawu otulutsa padziko lapansi a carboname ku China ndi matani oposa 10,000, zomwe zimawonetsa kotala yoposa ya zinthu zachilengedwe padziko lapansi, zomwe zimapangidwa padziko lapansi zamtengo wapatali kwambiri.
Crium Carbonate ndi mankhwala osokoneza bongo omwe ali ndi ma c3ce2o9, olemera olemera 46.40530, malo owiritsa a 196.80000 Popanga mafakitale adziko lapansi, cerium carbonate yapakati yokonza zinthu zosiyanasiyana zopangira cerium monga mchere wa cerium oxide. Imakhala ndi magwiritsidwe osiyanasiyana ndipo ndi chinthu chofunikira kwambiri padziko lapansi. Cryboate Crubote Burbonal Crybonal Cryboate Burbonal Cryboate Burbonal Cryboate Burbonal Crymon ya Lantanite, ndipo chithunzi chake sem chikuwonetsa kuti mawonekedwe a crium carbonal amtundu wambiri, ndipo mawonekedwewo ndi osavuta kutsukidwa mu zidutswa zazing'ono. Crium carbonate yomwe imapangidwa m'makampaniyo ili ndi 42-46% ya padziko lonse lapansi atayanika, zomwe zimalepheretsa kupanga crisbonate ya crium carbonate.
Mtundu wamadzi wotsika, mkhalidwe wokhazikika, wopangidwa ndi crium carbonate wosawuma, ndipo kuchuluka kwa dziko lapansi kumatha kuyanika 72%, ndipo njira imodzi yokonzekera carbonate yokwanira padziko lapansi. Dongosolo lotsatirali lakhazikitsidwa: Njira imodzi imagwiritsidwa ntchito kukonzekera crimon carbonate yokwanira padziko lapansi, ndiye kuti, ndi a ammonium, ndi a ammonium Kuchuluka kwa ammonium bicarbonate kumasinthidwa kotero kuti mtengo wa pH yamadzimadzi imasinthidwa pamapeto pake kusinthidwa mpaka 6.3 mpaka 6.5, ndipo kuchuluka kwake ndi koyenera kuti madzi am'madzi asamale. Njira yothetsera cerium yothetsera cerium chloride amadzimadzi yankho, ceum sulfate yankho kapena cerium yothetseratu. Gulu la R & D laurkalemes Tech. Co., ltd.
Crium Carbonate imatha kugwiritsidwa ntchito kukonzekera cerium oxide, crium dioxide ndi nanomatadium ina. Mapulogalamuwo ndi zitsanzo zili motere:
1. Kutengera kapangidwe ka koloko wamba Carbonate 0,4 ~ 1.2%, manganese dioxide 0.5 ~ 3%. Magalasi a 4mmmm ali ndi mawonekedwe owoneka bwino kwambiri kuposa 80%, kupatsirana kwa ultraviolet ochepera 15%, ndi kupatsirana ku Hoplengths of 568-590 nm kuposa 15%.
2. , 4 mpaka 10 za Titanium oxide, ma 4 mpaka 10 a Zircinia, 1 mpaka 5 a yttrium oxide, ndi 0,5 mpaka 5,5 mpaka ma gramium oxide. magawo, 0.01-1.5 a Kaolin, 0,01-1.5 Pomwe zida zapamwamba zapadziko lapansi zimaphatikizapo 0,01-1.5 a Lanthanum Carbonate, 0,01-15 mbali zina za Pragebonmium Carbonate, 0.01 mpaka 1.5 mpaka 1.5 mpaka 1.5 magawo a promethium nitrate; Zinthu zopanga filimu ndi potaziyamu sodium carbonate; Potaziyamu carbonate imasakanikirana ndi kulemera komweko kwa potaziyamu carbonate ndi sodicomu carbonate. Gawo lolemera la zosefera ndi zopanga mafilimu ndi 2.5: 7.5, 3.8: 6.2 kapena 4.8: 5. 5: 5.2: 5. Kupitilira apo, mtundu wa njira yokonzekera utoto wopulumutsa mphamvu yosungirako mphamvu imadziwika ndi zomwe zikugwirizana ndi izi:
Gawo 1 , 1 mpaka 5 za magnesium oxide, 0,8 mpaka 5 a Silicon Carbide, 0.0 mpaka 5 a Cromium Oxide Pomwe, zomwe zidachitika padziko lapansi zimaphatikizapo ziwalo za Lanthanum Carbonate, 0,01-1.5 magawo a Criboniate, 0,01-1.5
Gawo 2, Kukonzekera kwa zinthu zomwe makanema, zinthu zopangira mafilimu ndi sodium potaziyamu carbonate; Choyamba amalemera potaziyamu carbonate ndi sodium carbonate molemekeza, kenako sakanizani nawonso kuti apeze zinthu zopangira mafilimu; The sodium potaziyamu ndi kulemera komweko kwa potaziyamu carbonate ndi sodi carbonate wamitundu yosakanikirana;
Gawo 3, chiwerengero chosakanikirana cha filler ndi mawonekedwe a filimu ndi 2.5: 7.5, 6.8: 6.2 kapena 4.8: 5. 5: 5.2, ndipo osakaniza ali osakanizika osakanikirana kuti atenge kusakaniza;
Mu Gawo 4, osakaniza ali pamtunda wamtunda kwa maola 6-8, kenako chinthu chomalizidwa chimapezeka podutsa chophimba, ndipo maulalo a chophimba ndi 1-5.
3. Kukonzekera kwa cerafine ceraum oxide: kugwiritsa ntchito crium carbonate ya carbonate monga kukula kwa miliri ocheperako ndi kuchuluka kwa tinthu tambiri ochepera 3 μm adakonzedwa ndi kuchuluka kwa mpira ndi kuwerengetsa. Zogulitsa zonse zimakhala ndi mawonekedwe a cubic fluorite. Monga kutentha kwa kutentha kumawonjezeka, kukula kwazinthu zomwe zimachepa, tinthu tating'onoting'ono timene timafalikira ndipo makristal amakula. Komabe, kuthekera kwamphamvu kwa magalasi atatu osiyana kunawonetsa mtengo wapamwamba pakati pa 900 ℃ ndi 1000 ℃. Chifukwa chake, amakhulupirira kuti kuchotsa magalimoto agalasi pamtundu wa galasi pakupukuta kumakhudzidwa kwambiri ndi tinthu tating'onoting'ono, mawonekedwe a crystallity ndi pansi pa ufa wopukutira.
