Kuyambira m'ma 1950, Chinadziko lapansiOgwira ntchito ndi ukadaulo wa ukadaulo wachita kafukufuku wowonjezera ndi chitukuko pa njira yodzitchinjiriza yolekanitsadziko lapansiZotsatira zake, ndipo zakwaniritsa kafukufuku ambiri sayansi, zomwe zakhala zikugwiritsidwa ntchito kwambiri padziko lapansi mafakitale. Mu 1970, N263 idagwiritsidwa ntchito bwino m'makampani kuti ichotse ndi kupatukanaYTTRIAM OXIDNdi chiyero cha 99.99%, kusinthanitsa njira ya iyoni kuti alekanitseYTTRIAM OXID. Mtengowo unali wochepera gawo limodzi mwa magawo khumi a ion kusinthana njira; Mu 1970, P204 Cellction idagwiritsidwa ntchito m'malo mwa njira yobwezeretsanso njira yobwezeretsansodziko lapansi; KupezaLanthanum oxideKugwiritsa ntchito methyl Dimethyl Heptyl EST (P350) m'malo mwa njira ya crystal yodziwika; Mu 1970s, njira ya ammonia p507 pochotsa ndi kupatukana kwadziko lapansizinthu ndi kuchotsera kwaYNTriumNdi Naphic acid adagwiritsidwa ntchito koyamba ku Chinadziko lapansimabizinesi a Hydromallorgy; Kukula kwachangu kwa ukadaulo wambiri ku Chinadziko lapansiMakampani osagwirizana ndi ntchito yolimba ya Yuan Chengye ndi ma comwene ena ochokera ku China Academy of Science Shanghai Instistry. Zotulutsa zosiyanasiyana (monga P204, P350, P350, P350, ndi zina zambiri) afufuza bwino za ntchito kwambiri m'mafashoni; Cholinga cha Cascade Exprection chomwe chimafunsidwa ndikulimbikitsidwa ndi Pulofesa XU Guangxian of Pein University mu 1970s wasewera ku University ya China. Nthawi yomweyo, njira zolekanitsa zimakhazikika pogwiritsa ntchito chiphunzitso cha Cascade Podukiridwa ndi kugwiritsidwa ntchito kwambiri mudziko lapansiKutulutsa ndi makampani olekanitsa.
Zaka 40 zapitazi, China yakwaniritsa zinthu zambiri zodabwitsa m'munda wadziko lapansiKupatukana ndi kuyeretsa.
M'zaka za m'ma 1960, Beijing zopanda zitsulo zomwe adayambitsa ku Incritely adaphunzira bwino ufa wa alkalinity njira kuti apange oyeraEuropium oxide, yemwe anali koyamba ku China kuti apange zinthu zazikulu kuposa 99.99%. Njirayi imagwiritsidwabe ntchito mosiyanasiyanadziko lapansidziko lonse lomwe limagwiritsidwa ntchito ndi fakitale; Shanghai yueong mankhwala chomera, yunivesite ya Fudan, ndi Beijing General Metroous amagwira ntchito yoyamba kugwiritsa ntchito Enrich N263 ndikuchotsa kuyera kwa 99.95%.YTTRIAM OXID. Mu 1970, P204 idagwiritsidwa ntchito ku Enichi N263 ndikupezaYTTRIAM OXIDNdi kuyera kwa oposa 99.99% kudzera pachifuwa ndi kuyeretsa.
Kuyambira mu 1967 mpaka 1968, chomera choyesera cha Jiangxi 801 chitoliro chosakanizira chitole chofufuzira zomwe zimagwira ntchito moyenera kuti mugwiritse ntchito popanga ma p204. Mu Disembala 1968, matani atatu a Ton / car yYTTRIAM OXIDZochita zopanga zidamangidwa, ndi chiyero cha 99% yaYTTRIAM OXID.
Mu 1972, gulu lofufuzira linapangidwa ndi makampani anayi, kuphatikizapo Beijing yofufuzira itafufuto, chithunzi cha Jiangxi 806, Jiangxi Noniferous Metalducy wopanga inshuwaransi. Pambuyo pa zaka ziwiri zoyesa zoyeserera ku BeijingYTTRIAM OXIDKugwiritsa ntchito Naphini acid monga mowa wophatikizika ndi mowa womwe umagwiritsidwa ntchito udaphunzirira bwino.
Mu 1974, Changuzun Institute of Mapertery Chemistry adapeza nthawi yoyamba kuti kulekanitsadziko lapansizinthu zomwe zimagwiritsa ntchito acid acid acid,YNTriumanali kutsogolo kwaLanthanum, kupangitsa kuti ikhale yosavuta mosavuta mu zinthu zazing'ono kwambiri padziko lapansi. Chifukwa chake, ukadaulo wolekanitsaYTTRIAM OXIDKugwiritsa ntchito 8 acid acid kuchokera ku asidi a Nitric acid adafunsidwa. Nthawi yomweyo, ku BeijingYTTRIAM OXIDKuchokera ku hydrochloric acidys amagwiritsa ntchito Naphsuin acid, ndipo zoyeserera zokutira zidachitidwa ku Nanung 603 chomera ndi jiujiang 806, pogwiritsa ntchito uleosowa kwambiri oxidemonga zosaphika. Mu 1974, Shanghai yueong mankhwala chomera, yunivesite ya Fudan, ndi Beijing Searchlent Schoarch Institute Institute kuti aphunzire kulekanitsa kwaYTTRIum oxide kuchokera ku Montazite wosakanikiranadziko lapansiwa bulauniYNTriumcolumbium ore imagwiritsa ntchito kwambiridziko lapansizopangidwa ndi gulu la P204 monga chomera, ndipoYTTRIum oxide amalekanitsidwa ndi epfinic acid. Mpikisano waubwenzi unachitika pakati pa anthu atatu, pomwe aliyense adasinthana ndi zofooka ndi zofooka za wina ndi mnzake, ndipo pomaliza adaphunzira bwino acifuno ndi njira zolekanitsidwa ndi 99.99%YTTRIum oxide ndi mawonekedwe aku China.
Kuyambira 1974 mpaka 1975, NanChang 603YTTRIum oxide Kuchotsa njira - Naphtheiny acid imodzi-gawo lonse ndi m'zigawo za oyera kwambiriYTTRIum oxide. Njirayi idagwiritsidwa ntchito mu 1976.
Padziko LoyambaDziko lapansiMisonkhano ya Crat in Baotou mu 1976, a XU Guangxian adaganiza chiphunzitso cha ma cascade. Mu 1977, mawu oti mayina a NationalDziko lapansiKuchotsa Chiphunzitso ndi Kuchita "kunachitika ku Shanghai yueeng hueeong mankhwala chomera, kupereka mawu oyambira komanso okwanira ku lingaliro ili. Pambuyo pake, chiphunzitso cha Cascade Expoidacho chinagwiritsidwa ntchito kwambiri pakufufuza komanso kupanga kwa chowonjezera padziko lapansi, ndikuyeretsa.
Mu 1976, Beijing Storferous Meditetion Institute Institute amagwiritsa ntchito Baotou Ore Oreted ndidziko lapansiKutulutsaceumkuchokera pazinthu zopanduka. Njira ya N263 idagwiritsidwa ntchito kupatukanaLanthanum Praseymium Newdyoum. Zinthu zitatu zinalekanitsidwa mu chofuula chimodzi, komanso chiyero chaLanthanum oxide, Prageymium oxide, ndipoNewdymium oxideanali pafupifupi 90%.
Kuyambira 1979 mpaka 1983, BaotouDziko lapansiKafukufuku wofufuza komanso Beijing Sharedrous Carchle Institute adapanga P507 Hydrochloric acid systemsdziko lapansiKulekanitsidwa njira yolekanitsa pogwiritsa ntchito Baotou Rarernroser Or Ore monga riwtor kuti apeze sikisidziko lapansiZogulitsa (zoyera 99% mpaka 99.95%) yaLanthanum, ceum, Praseymium, Newdyoum, mhamarium, ndipogadolinium, komansoEuropiumndimnyangazopangidwa ndi zinthu. Njirayi inali yayifupi, zopitilira, ndi zoyera zamasamba zinali zazitali.
Kumayambiriro kwa m'ma 1980, ku Beijingdziko lapansiZinthu zochokera ku Lostan zosakanizadziko lapansiKugwiritsa ntchito P507 hydrochloric acid sysy.
Mu 1983, a Jiujiang sapereka zitsulo zonunkhira zomwe zimatengera ukadaulo wa BeijingYTTRIAM OXIDKuchokera ku Lostan Mosakaniza dziko lapansi loipa "kuti apange kalasiYTTRIAM OXID, kuchepetsa mtengo waYTTRIAM OXIDndi kukumana ndi zomwe akufunaYTTRIAM OXIDpa TV ku China.
Mu 1984, Beijing General Institute ya zitsulo zopanda mphamvu zomwe zimathandizira kupatukana kwa chiyero chachikuluTerbium oxideKugwiritsa ntchito PER50Y Certin KugulitsamnyangaZinthu zolemetsa monga zopangira ku China.
Mu 1985, Beijing zopanda zitsulo zofufuzira Institutes adasamutsa acid acid Edelction kupatukana fluorescent kalasiYTTRIAM OXIDMakina aukadaulo kwa Democratic Republic ku German Republic kwa 1.71 miliyoni a Swiss Francs, yomwe inali yoyambadziko lapansiTekinoloje yolekanitsa kunja kwa China.
Kuyambira 1984 mpaka 1986, penga ku yunivesite yoyeserera mafakitale pacholekanitsidwa ndi kupatukana ndi la la / ce / pr ndi prcl dongosolo lachitatuDziko lapansiChomera cha baosteli. Oposa 98%Prageymium oxide, 99.5%Lanthanum oxide, opitilira 85%Cerium Oxide, ndi 99%Newdymium oxideadapezeka. Mu 1986, Shanghai yueong mankhwala chomera chimagwiritsa ntchito njira yotsatsira itatu yopanga ma yunivesite, kuti ayesetse mafakitale atatu a Purcade Padziko Lonse Lapansi Padziko Lonse Lapansi. Kuyesa kwa mafakitale kumawonjezera chiphunzitso cha Cascade pochotsa matani 100 matani, kufupikitsa kuzungulira komwe kumagwiritsa ntchito njira yatsopano kupanga.
Kuyambira mu 1986 mpaka 1989, Baotou Rerusalearch Search, Jiangxir 603 Fakitala Yofufuza Institute adapanga njira yotulutsa ma p577-Hiple padziko lapansi kudzera m'zigawo zingapo. Njirayi ndiyochepa, yotsika mtengo, komanso yosinthika.
Kuyambira mu 1990 mpaka 1995, Beijing Sharedrous Search Carchtutes ndi BaotouDziko lapansiKafukufuku wofufuza zinthu adagwirizana kuti achite "dongosolo la chaka chachisanu ndi chitatuDziko lapansiChiphunzitso chodukitsira ". Asanu ndi umodziosowa kwambiri oxideZogulitsa zokhala ndi zoyera kuposa 99.999% mpaka 99.999% idakonzedwa kugwiritsa ntchito njira yowonjezera, njira yosinthira ya ma chromatoraphy, motsatana. Njirayi yafika pamlingo wapadziko lonse lapansi ndipo wapambana National "ENAGE chaka chitatu.
Mu 2000, Beijing zopanda zitsulo zofufuza zomwe adayambitsa bwino adapanga bwino ma electrolytic alkalinity njira yokonzekeretsa kwambiriEuropium oxide. Chifukwa chopewa kuipitsa kwa zinc ufa pazinthu, njirayi imatha kutulutsaEuropium oxideNdi kuyera kwa 5n-6n konse kumapita. Mu 2001, mzere wopangidwa wapachaka wa matani 18 a matani apamwamba kwambiriEuropium oxideadamangidwa ku GayuDziko lapansiKampani ndikugwirira ntchito chaka chimenecho.
