Chiirare pasi?
Vanhu vane nhoroondo yeanopfuura mazana maviri emakore kubvira pakuwanikwa kwevanhu vepanyika muna 1794. Sezvo pakanga paine vashoma vasingabvumirwe kwenguva yakati rebonde midziyo inogona kuwanikwa inogona kuwanikwa nenzira yemakemikari. Nenhoroondo, nzombe dzakadai dzaitorwa dzichinzi "pasi", saka zita revapasi pasirese.
Muchokwadi, zvisingawanzo-Pasi Mineral hazvigone kujairika mune zvakasikwa. Pasi pevhu haisi yepasi, asi yakajairwa simbi chinhu. Yayo inoshanda mhando chete yechipiri kuAlkali simbi uye alkaline pasi simbi. Ivo vane zvakawanda zvemukati mukuputika kupfuura mhuka dzakatangira, zinc, tin, cobalt, uye nickel.
Parizvino, nyika isingawanzo shandiswa zvakanyanya munzvimbo dzakasiyana siyana seyemagetsi, metallocal makore 35, masayendisiti anokwanisa kuwana mashandisiro okunze, uye kubva pane zvese zvitanhatu zvigadzirwa, munhu haagoni kuita pasina nyika.
China hupfumi muPrit muKashoma Pasi Zvicherwa, chinzvimbo chekutanga mune nhatu dzeWorld Workings: Reservation, kugadzirwa kwemaitiro, uye kunze kwenyika. Panguva imwecheteyo, China zvakare iyo nyika chete inogona kupa ese gumi nematanhatu simbi simbi, kunyanya svikiro uye inorema pasi pano pasi zvine mukurumbira wemauto.
Risingawanzo kugadzirwa kwepasi
Zvisingawanzogadzirwa zvepasi zvinhu zvinoumbwa nezvinhu zveLannades mune iyo nguva yemapato yezvinhu zvemakemikari zvinhu:Lanthanum(LA),cerium(CE),Praseodymiyo(Pr),neodymium(ND), Promethium (PM),Samarium(SM),Europium(EU),Gadolinium(GD),terbium(Tb),Dysprosium(DY),Holmium(Ho),erbium(ER),thumi(Tm),ytterbium(Yb),lutetium(Lu), uye zvinhu zviviri zvine chekuita neLananide:Scandium(SC) uyeytrium(Y).
InonziRare pasi, yakajeka sevhu risina chinhu.

Zvivakwa zvezvinhu zvisingawanzo kuitika zvepasi
Kupfuura makumi mashanu mabasa ezvinhu zvisingawanzo kuitika kune yavo yakasarudzika 4F chimiro, ichiita kuti vashandiswe zvakanyanya mune zvese zvetsika zvinhu uye zvakakwirira-tech mitsva minda mitsva yeminda.
4f Electron orbit
1. Zvepanyama uye zvemakemikari zvivakwa
★ ine zvigadziko zvesimbi zviri pachena; Iyo sirivha grey, kunze kweiyo praseodymium uye neodymium, inoratidzika yero yero
★ pfuma oxide mavara
★ fomu yakagadzikana makomputa neisiri-simbi
★ Metal Lively
★ Easy kune oxidize mumhepo
2 Optoelectronic Properties
★ Isina kukwana 4F Sublayer, uko maElef Electrons anochengetedzwa neyemagetsi ekunze, zvichikonzera mumhando dzakasiyana siyana uye esimba mazinga
Kana 4F Electrons shanduko, vanokwanisa kutora kana kubvisa radiation yemavhiri akasiyana kubva kuUllengths
★ yakanaka yekuita, inokwanisa kugadzirira nyika isingawanzo simbi nemagetsi nzira
Basa re 4F emagetsi emagetsi emagetsi zvisingawanzo kuitika zvinhu zviri muzvinhu zvitsva
1.materials inoshanda 4F zvemagetsi maficha
★ 4f Electron Spin gadziriro:inoratidzwa semagineti yakasimba - yakakodzera kushandiswa seyisingagumi magnet zvinhu, MRI Kufungidzira Zvigadzirwa, Magineti Sensors, SuperConductors, nezvimwewo, nezvimwewo
★ 4F orbital electron shanduko.
Shanduko yemagetsi mune iyo 4F Energy Level Guide Band: inoratidzwa seyakagadziriswa zvivakwa - yakakodzera kuti uve nenhamba uye yekushongedza nzvimbo dzinopisa, dzenzvimbo dzinopisa, girazi rezvemafuta, girazi, nezvimwewo, nezvimwewo
2 inongoenderana neyakaenderana ne 4F elektron, uchishandisa Ionic radius, kubhadharisa uye makemikari zvivakwa
★ Nyukireya hunhu:
Chidiki Thermal neutron chinobata chikamu chekuyambuka - chakakodzera kushandiswa sechinhu chakarongeka chevanorega venyukireya, nezvimwe
Yakakura neutorning kuyambuka chikamu chekuyambuka - yakakodzera kuzvidzora zvigadzirwa zve nyukireya englear, nezvimwe
★ Rare Earth ionic radius, mhondi, yemuviri uye makemikari zvivakwa:
Lattice urema, zvakafanana Ionic radius, zvimiro zvemakemikari, zvakavanzika - zvakakodzera kupisa, catalyst, etc
Rudzi rwechokwadi - yakakodzera kushandiswa seHydrogen Chengetedza Alloy Cathode Zvigadzirwa, Microwave Yekutanga Zvinhu, Etc
Electro Optical neDilelectric Zvivakwa - Inokodzera kushandiswa seyakajeka modulation zvinhu, pachena cereracs, nezvimwe
