Uhlu lwezinto eziyi-17 ezingavamile ezisetshenziswayo (ezinezithombe)

Aisingathekiso esivamile siwukuthi uma uwoyela uyigazi lemboni, khona-ke umhlaba ongavamile uyivithamini yezimboni.

Umhlaba ongavamile isifinyezo seqembu lezinsimbi. I-Rare Earth Elements,REE) itholakale ngokulandelana kusukela ekupheleni kwekhulu le-18. Kunezinhlobo ezingu-17 ze-REE, okuhlanganisa ama-lanthanide angu-15 kuthebula le-periodic lama-elementi amakhemikhali-lanthanum (La), i-cerium (Ce), i-praseodymium (Pr), i-neodymium (Nd), i-promethium (Pm), njalonjaloOkwamanje, isetshenziswe kabanzi emikhakheni eminingi efana ne-electronics, petrochemicals kanye ne-metallurgy. Cishe njalo eminyakeni engu-3-5, ososayensi bangathola ukusetshenziswa okusha komhlaba ongavamile, futhi okusungulwe okukodwa kweziyisithupha akukwazi ukuhlukaniswa nomhlaba ongavamile.

umhlaba ongavamile 1

IShayina inothe ngezimbiwa phansi eziyivelakancane, ikleliswe kuqala emazweni amathathu: eyokuqala ezindaweni ezigcina izinsiza, ibalwa cishe ngama-23%; Umphumela ungowokuqala, uhlanganisa amaphesenti angama-80 kuya kwangama-90 ezinto zomhlaba eziyivelakancane; Ivolumu yokuthengisa ingeyokuqala, ngama-60% kuya ku-70% wemikhiqizo yomhlaba eyivelakancane ethunyelwa phesheya. Ngesikhathi esifanayo, iShayina ukuphela kwezwe elingahlinzeka ngazo zonke izinhlobo eziyi-17 zezinsimbi zomhlaba eziyivelakancane, ikakhulukazi umhlaba ongavamile ophakathi nendawo nosindayo onokusetshenziswa okuvelele kwezempi.Isabelo seShayina siyathandeka.

RUmhlaba uwumthombo obalulekile wamasu, owaziwa ngokuthi “industrial monosodium glutamate” kanye “nonina wezinto ezintsha”, futhi usetshenziswa kabanzi kwezesayensi nobuchwepheshe nezimboni zezempi. Ngokusho koMnyango Wezimboni Nobuchwepheshe Bolwazi, izinto ezisebenzayo ezinjengozibuthe ongapheli womhlaba, i-luminescence, isitoreji se-hydrogen kanye ne-catalysis seziphenduke izinto ezingabalulekile ezimbonini zobuchwepheshe obuphezulu njengokukhiqiza imishini ethuthukisiwe, amandla amasha nezimboni ezisafufusa. esetshenziswa kabanzi kwezobuchwepheshe, imboni ye-petrochemical, i-metallurgy, imishini, amandla amasha, imboni yokukhanya, ukuvikelwa kwemvelo, ezolimo nokunye. .

Kusukela ngo-1983, i-Japan yethula uhlelo lwesu lokugcina amaminerali angavamile, futhi ama-83% omhlaba ongavamile wasekhaya avela e-China.

Bheka futhi i-United States, iziqiwu zayo zomhlaba ezingavamile zingelesibili ngemva kweShayina, kodwa umhlaba wayo ongavamile wonke umhlaba ongavamile okhanyayo, ohlukaniswe waba yimihlaba enzima engavamile kanye nomhlaba ongavamile okhanyayo. Imihlaba enzima eyivelakancane ibiza kakhulu, futhi imihlaba engavamile ekhanyayo ayinawo umnotho kweyami, osekuphendulwe umhlaba oyinqaba womgunyathi ngabantu abasembonini. Ama-80% omhlaba avela e-US avela eChina.

UComrade Deng Xiaoping wake wathi: “Kukhona uwoyela eMpumalanga Ephakathi nomhlaba oyivelakancane eChina.” Okushiwo amazwi akhe kusobala. I-Rare Earth akuyona nje i-“MSG” edingekayo ye-1/5 yemikhiqizo yobuchwepheshe obuphezulu emhlabeni, kodwa futhi iyi-bargaining chip enamandla ye-China etafuleni lezingxoxo zomhlaba esikhathini esizayo. Vikela futhi usebenzise ngokwesayensi imithombo yomhlaba eyivelakancane, Sekuyisu lezwe elibizwe abantu abaningi abanemibono ephakeme eminyakeni yamuva nje ukuvimbela imithombo yomhlaba eyigugu engavamile ukuba ithengiswe ngokungaboni futhi ithunyelwe emazweni asentshonalanga. Ngo-1992, u-Deng Xiaoping wasichaza ngokucacile isimo se-China njengezwe elikhulu lomhlaba eliyivelakancane.

I-Scandium (Sc)

26 Sc

I-Metal scandium (imephu yedatha)

Uma kuqhathaniswa nezakhi ze-yttrium ne-lanthanide, i-scandium inobubanzi obuncane be-ionic kanye ne-alkalinity ebuthakathaka ikakhulukazi ye-hydroxide. Ngakho-ke, lapho i-scandium nezakhi zomhlaba ezingavamile kuhlanganiswa ndawonye, ​​i-scandium izokwehla kuqala uma iphathwa nge-ammonia (noma i-alkali ehlanjululwe ngokwedlulele), ngakho-ke ingahlukaniswa kalula nezakhi zomhlaba ezingavamile ngendlela "yemvula eyingxenye". Enye indlela ukusebenzisa i-polarization decomposition of nitrate for separation.Scandium nitrate iyona elula kakhulu ukubola, ngaleyo ndlela ifinyelele injongo yokuhlukana.

I-Sc ingatholwa nge-electrolysis. I-ScCl3, KCl kanye ne-LiCl ziyancibilika ngesikhathi sokucwengwa kwe-scandium, futhi i-zinc encibilikisiwe isetshenziswa njenge-cathode ye-electrolysis, ukuze i-scandium idonswe ku-electrode ye-zinc, bese i-zinc iyahwamuka ukuze kutholwe i-scandium. Ngaphezu kwalokho, i-scandium itholakala kalula lapho icutshungulwa i-ore ukuze ikhiqize i-uranium, i-thorium ne-lanthanide izakhi. Ukutholwa okuphelele kwe-scandium ehlobene ne-tungsten ne-tin ore nakho kungenye yemithombo ebalulekile ye-scandium.I-Scandium i-misesimweni se-trivalent esakhiweni, esifakwa kalula kwi-Sc2O3 emoyeni futhi ilahlekelwe ukucwebezela kwayo kwensimbi bese iphenduka ibe mpunga obumnyama. 

Ukusetshenziswa okuyinhloko kwe-scandium yizi:

(1) I-Scandium ingasabela emanzini ashisayo ukuze ikhulule i-hydrogen, futhi iphinde inyibilike ku-asidi, ngakho iyi-ejenti yokunciphisa enamandla.

(2) I<em>Scandium oxide ne-hydroxide kune-alkaline kuphela, kodwa umlotha wayo kasawoti awukwazi ukukhishwa nge-hydrolyzed. I-Scandium chloride iyikristalu emhlophe, encibilika emanzini futhi i-deliquescent emoyeni. (3) Embonini ye-metallurgical, i-scandium ivame ukusetshenziselwa ukwenza ama-alloys (izithasiselo zama-alloys) ukuthuthukisa amandla, ubulukhuni, ukumelana nokushisa nokusebenza kwama-alloys. Isibonelo, ukwengeza inani elincane le-scandium ensimbi encibilikisiwe kungathuthukisa kakhulu izakhiwo zensimbi ekhonjiwe, kuyilapho ukwengeza inani elincane le-scandium ku-aluminium kungathuthukisa amandla ayo nokumelana nokushisa.

(4) Embonini ye-elekthronikhi, i-scandium ingasetshenziswa njengamadivayisi ahlukahlukene we-semiconductor. Isibonelo, ukusetshenziswa kwe-scandium sulfite kuma-semiconductors kuye kwaheha ukunaka ekhaya nakwamanye amazwe, futhi i-ferrite equkethe i-scandium nayo iyathembisa.i-computer magnetic cores. 

(5) Embonini yamakhemikhali, i-scandium compound isetshenziswa njenge-alcohol dehydrogenation kanye ne-ejenti yokuqeda amanzi emzimbeni, okuyi-catalyst ephumelelayo yokukhiqizwa kwe-ethylene ne-chlorine kusuka kudoti i-hydrochloric acid. 

(6) Embonini yengilazi, izibuko ezikhethekile eziqukethe i-scandium zingenziwa. 

(7) Embonini yomthombo wokukhanya kagesi, izibani ze-scandium ne-sodium ezenziwe nge-scandium ne-sodium zinezinzuzo zokusebenza kahle kakhulu nombala wokukhanya omuhle. 

(8) I-Scandium ikhona ngesimo se-45Sc ngemvelo. Ngaphezu kwalokho, kukhona ama-isotopes ayisishiyagalolunye anemisebe e-Scandium, okuyi-40~44Sc kanye ne-46~49Sc. Phakathi kwazo, i-46Sc, njenge-tracer, isetshenziswe embonini yamakhemikhali, i-metallurgy kanye ne-oceanography. Kwezokwelapha, kunabantu baphesheya abafunda besebenzisa i-46Sc ukwelapha umdlavuza.
