Afanizo lodziwika bwino ndiloti ngati mafuta ndi magazi a mafakitale, ndiye kuti dziko lapansi losowa ndilo vitamini wamakampani.
Dziko lapansi osowa ndi chidule cha gulu la zitsulo. Rare Earth Elements,REE) zapezeka motsatizana kuyambira kumapeto kwa zaka za zana la 18. Pali mitundu 17 ya REE, kuphatikiza 15 lanthanides mu periodic table of chemical elements-lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), ndi zina zotero akhala akugwiritsidwa ntchito kwambiri m'magawo ambiri monga zamagetsi, petrochemicals ndi zitsulo. Pafupifupi zaka 3-5 zilizonse, asayansi amatha kupeza ntchito zatsopano zapadziko lapansi, ndipo chimodzi mwazinthu zisanu ndi chimodzi zilizonse sichingasiyanitsidwe ndi dziko losowa.
China ili ndi mchere wambiri wapadziko lapansi, womwe umakhala woyamba padziko lonse lapansi: woyamba m'malo osungiramo zinthu, womwe umakhala pafupifupi 23%; Kutulutsa kwake ndi koyamba, komwe kumatenga 80% mpaka 90% ya zinthu zomwe sizipezeka padziko lonse lapansi; Voliyumu yogulitsa ndi yoyamba, yokhala ndi 60% mpaka 70% yazinthu zomwe zasowa padziko lapansi zomwe zimatumizidwa kunja. Panthawi imodzimodziyo, dziko la China ndilo dziko lokhalo lomwe lingapereke mitundu yonse ya 17 yazitsulo zapadziko lapansi, makamaka zapakatikati ndi zolemera zapadziko lapansi zomwe zimagwiritsidwa ntchito kwambiri ndi asilikali.
RDziko lapansi ndi chida chamtengo wapatali, chomwe chimadziwika kuti "industrial monosodium glutamate" ndi "mayi wazinthu zatsopano", ndipo chimagwiritsidwa ntchito kwambiri mu sayansi yaukadaulo ndiukadaulo komanso mafakitale ankhondo. Malinga ndi Unduna wa Zamakampani ndi Ukadaulo Wachidziwitso, zida zogwirira ntchito monga maginito osowa padziko lapansi, luminescence, kusungirako ma hydrogen ndi catalysis zakhala zofunikira kwambiri pamafakitale apamwamba kwambiri monga kupanga zida zapamwamba, mphamvu zatsopano ndi mafakitale omwe akubwera. amagwiritsidwa ntchito kwambiri mu zamagetsi, mafakitale a petrochemical, zitsulo, makina, mphamvu zatsopano, makampani owunikira, kuteteza chilengedwe, ulimi ndi zina zotero. .
Kumayambiriro kwa 1983, Japan idayambitsa njira yosungiramo mchere wosowa, ndipo 83% ya nthaka yake yapakhomo idachokera ku China.
Tayang'ananinso ku United States, malo ake osungira nthaka osowa ali achiwiri ku China, koma dziko lake losowa ndilo dziko lapansi losowa, lomwe limagawidwa kukhala dziko lapansi lolemera kwambiri ndi dziko lapansi losowa. Dziko lapansi lolemera kwambiri ndi lokwera mtengo kwambiri, ndipo zopepuka zapadziko lapansi ndizopanda chuma kwanga, zomwe zasandutsidwa nthaka yabodza ndi anthu ogulitsa. 80% ya zinthu zachilendo zaku US zochokera kunja zimachokera ku China.
Comrade Deng Xiaoping ananenapo kuti: “Ku Middle East kuli mafuta ndiponso nthaka yosowa kwambiri ku China.” Tanthauzo la mawu ake ndi lodziwikiratu. Dziko losawerengeka silofunika kokha "MSG" ya 1/5 yapamwamba kwambiri padziko lonse lapansi, komanso chida champhamvu chamalonda cha China patebulo lokambirana padziko lonse lapansi mtsogolomu. Tetezani ndikugwiritsa ntchito mwasayansi zopezeka zapadziko lapansi, yakhala njira yadziko yomwe anthu ambiri omwe ali ndi malingaliro apamwamba mzaka zaposachedwa aletsa kuti zinthu zamtengo wapatali zapadziko lapansi zisagulitsidwe ndikutumizidwa kumayiko akumadzulo. Mu 1992, Deng Xiaoping adanena momveka bwino kuti dziko la China ndi dziko losowa kwambiri padziko lapansi.

Scandium (Sc)
Metal scandium (mapu a data)
Poyerekeza ndi zinthu za yttrium ndi lanthanide, scandium ili ndi radius yaying'ono kwambiri komanso alkalinity yofooka kwambiri ya hydroxide. Chifukwa chake, scandium ndi zinthu zapadziko lapansi zosowa zitasakanizidwa, scandium imayamba kutsika ikathandizidwa ndi ammonia (kapena kusungunula kwambiri alkali), kotero imatha kulekanitsidwa mosavuta ndi zinthu zapadziko lapansi zomwe sizipezeka mwa njira ya "fractional precipitation". Njira ina ndiyo kugwiritsa ntchito polarization decomposition of nitrate for separation.Scandium nitrate ndi yosavuta kuwola, motero kukwaniritsa cholinga cha kulekana.
Sc ikhoza kupezedwa ndi electrolysis. ScCl3, KCl ndi LiCl zimasungunuka panthawi yoyengedwa ndi scandium, ndipo zinki yosungunuka imagwiritsidwa ntchito ngati cathode ya electrolysis, kotero kuti scandium imadutsa pa electrode ya zinki, ndiyeno zinki imasungunuka kuti ipeze scandium. Kuphatikiza apo, scandium imapezedwa mosavuta pokonza miyala kuti ipange uranium, thorium ndi lanthanide zinthu. Kuchira kwathunthu kwa scandium yogwirizana kuchokera ku tungsten ndi malata ndi chimodzi mwazinthu zofunika kwambiri za scandium.Scandium ndi m.ainly mu trivalent state mu pawiri, amene ali oxidized mosavuta Sc2O3 mu mpweya ndipo amataya zitsulo zonyezimira ndi kusanduka imvi mdima.
Ntchito zazikulu za scandium ndi:
(1) Scandium imatha kuchitapo kanthu ndi madzi otentha kuti itulutse haidrojeni, komanso imasungunuka mu asidi, motero imakhala yochepetsera kwambiri.
(2) Scandium oxide ndi hydroxide ndi zamchere zokha, koma phulusa lake lamchere silingathe kupangidwa ndi hydrolyzed. Scandium chloride ndi kristalo woyera, wosungunuka m'madzi komanso wonyezimira mumlengalenga. (3) M'makampani opanga zitsulo, scandium nthawi zambiri imagwiritsidwa ntchito popanga ma alloys (zowonjezera za aloyi) kuti apititse patsogolo mphamvu, kuuma, kukana kutentha ndi magwiridwe antchito a aloyi. Mwachitsanzo, kuwonjezera kachulukidwe kakang'ono ka chitsulo chosungunula kumatha kusintha kwambiri zinthu zachitsulo chosungunuka, pomwe kuwonjezera kachulukidwe kakang'ono ku aluminiyamu kumatha kukulitsa mphamvu zake komanso kukana kutentha.
(4) Mu makampani amagetsi, scandium ingagwiritsidwe ntchito ngati zipangizo zosiyanasiyana za semiconductor. Mwachitsanzo, kugwiritsa ntchito scandium sulfite mu semiconductors kwakopa chidwi kunyumba ndi kunja, ndipo ferrite yomwe ili ndi scandium ikulonjezanso.kompyuta maginito cores.
(5) Mumakampani opanga mankhwala, scandium pawiri imagwiritsidwa ntchito ngati mowa dehydrogenation ndi dehydration agent, yomwe ndi chothandizira chothandizira kupanga ethylene ndi chlorine kuchokera ku zinyalala za hydrochloric acid.
(6) M'makampani agalasi, magalasi apadera okhala ndi scandium amatha kupangidwa.
(7) M'makampani opangira magetsi, nyali za scandium ndi sodium zopangidwa ndi scandium ndi sodium zili ndi ubwino wochita bwino kwambiri komanso kuwala kowala bwino.
(8) Scandium ilipo mu mawonekedwe a 45Sc mu chilengedwe. Kuphatikiza apo, pali ma isotopu asanu ndi anayi a Scandium, omwe ndi 40 ~ 44Sc ndi 46 ~ 49Sc. Pakati pawo, 46Sc, ngati tracer, yagwiritsidwa ntchito mumakampani opanga mankhwala, zitsulo ndi zojambulajambula. Zamankhwala, pali anthu akunja omwe amaphunzira kugwiritsa ntchito 46Sc kuchiza khansa.
