Matsenga Oipa Padziko Lapansi: "Mfumu ya Magnetnet Okhazikika"

bastnasite

Newdymium, atomiki nambala 60, atomiki kulemera 144.24, ndi zomwe zili ndi 0,00239% mu kutumphuka, makamaka ku Montazite ndi Bastnasite. Pali Atotopes asanu ndi awiri a ku Nonentium m'chilengedwe: Ndodymium 142, 144, 145, 148, 148, pakati pa Newymium yomwe ili ndi zolengedwa zapamwamba kwambiri. Kubadwa kwa Pragesoodmuum, Ninymium kunayamba kukhala. Kufika ku Ndentymium kunayambitsa munda wa dziko lapansi ndipo kunagwira ntchito yofunika kwambiri.

Kupezeka kwa Nedymium

Karl Orvon WelsbAch (1858-1929), katulukidwe ka Newdymium

Mu 1885, katswiri wazamankhwala wa ku Austl Orlbon Wellbach Carl Vonsbach adazindikira ku Viedna. Analekanitsa ku Ninmedium ndi Prageymium kuchokera ku symmetric zida za ku Nemmentium polekanitsa ndi kuphatikizira ammonium nitrate tetrahhyd tetrahyd tetrahyd tetrahyd tetrahyd tetrahyd tetrahyd tetrahyd tetrahyd tetrahyd tetrahyd tetrahyd tets

Kuyambira m'ma 1950s, Newyedmium yayitali (oposa 99%) idapezeka ndi ion kulembetsa ku Montazite. Zitsulo zokhazokha zimapezeka ndi magetsi osadukiza mchere wake. Pakadali pano, ku Newdymium kwambiri kumachotsedwa (CE, LD, PR) ku Basta Nathathanite ndikuyeretsedwa ndi kuchotsera. Kusintha kwa kusintha kwa Ioon Kusungako koyera kwambiri (nthawi zambiri> 99.99%) Pokonzekera kutembenuka kotsiriza kwa nyengo ya ma crysmium komwe kumapangidwa ndi mtundu wamakono.

Zitsulo za Newdymium

Metallic Newdymium ili ndi siliva yowala ya saltillic, yosungunuka ya 1024 ° C, kachulukidwe ka 7.004 g / cm, ndi paramagnetism. Newdymium ndi amodzi mwa zitsulo zogwira kwambiri zapadziko lapansi, zomwe zimayamba mwachangu komanso zimapangitsa kuti oxisidisisiye wosungunuka, ndikutulutsa zitsulo kuti zitheke. Chifukwa chake, ku Newdymium zitsanzo ndi kukula kwa gawo limodzi la sentimita imodzi mwa chaka chimodzi. Imayamba pang'onopang'ono m'madzi ozizira komanso mwachangu m'madzi otentha.

Kukhazikitsa kwa Newdymium Electronic

Kukhazikitsa kwa Electronic:

1s2 2s2 2p6 3s2 3p2 4s2 3D10 4p6 5s2 4p6 6p2

Magwiridwe antchito a nedymium amayamba chifukwa cha ma elekiti a 4f orbital pakati pa magawo osiyanasiyana. Zomwe zidagwiritsidwa ntchito kwambiri polumikizidwa, zosungirako za chidziwitso, chithandizo chamankhwala, chamankhwala, ytt.

Kugwiritsa ntchito Nedymium

Wogwiritsa ntchito Nentymium ndi zinthu zakuthambo zakunja. Ndfeb Magnet imatchedwa "mfumu yazipatso zokhazikika" chifukwa cha mphamvu yake yayikulu. Amagwiritsidwa ntchito kwambiri pamagetsi, makina ndi mafakitale ena chifukwa cha ntchito yake yabwino. Khoma la Francis, pulofesa wa migodi ku Cumberland Sukulu ya Migodi, University of Exetsland

Newdymium Magnet pa Hard Disk

Newdymium itha kugwiritsidwa ntchito popanga ceramics, galasi lofiirira lofiirira, ruby ​​yopanga mu laser ndi galasi lapadera lomwe lingasesere khwangwala. Amagwiritsidwa ntchito limodzi ndi Pragesodymium kuti apangitse magalasi owomba magalasi.

Kuonjezera 1.5% ~ 2.5% nano nedymium oxide mu magnesium kapena aluminium alnoy amatha kusintha kutentha kwambiri, ndipo amagwiritsidwa ntchito kwambiri ngati arosseace zinthu zopangira ndege.

Nano-yttrium aluminium Garnet avala ndi nano-nedymaum wokwera mtengo wowerengeka, womwe umagwiritsidwa ntchito kwambiri poloza ndikudula zinthu zopyapyala ndi makulidwe aliwonse.

ND: YAG Laser ndodo

Mu mankhwala azachipatala, nano yttrium alminium adyoni laser amatulutsidwa ndi nano nedymum orograium amagwiritsidwa ntchito kuchotsa mabala opaleshoni kapena mabala a mankhwala opatsirana m'malo mwa mipeni ya opaleshoni.

Galasi la Ninsmium limapangidwa powonjezera Newdmium oxide mugalu. Lavender nthawi zambiri imawoneka mu galasi la Newdmium padzuwa kapena nyali ya incandescent, koma lamchere imawoneka pansi pa ma fluoresyer kuwunikira kwa fluorescent. Newdymium imatha kugwiritsidwa ntchito ngati mitundu yosalala yagalasi monga violet yoyera, vinyo wofiira komanso imvi yotentha.

galasi la Newymium

Ndi chitukuko cha sayansi ndi ukadaulo ndi kufalikira ndi kuchuluka kwa sayansi ndi ukadaulo wapadziko lapansi, Newdymium idzakhala ndi malo owonjezera
