Newdymium ndi amodzi mwa zitsulo zodziwika kwambiri zapadziko lapansi

Mu 1839, cgmosander cgmosander idazindikira kusakaniza kwa lanthemum (LAN) ndi Prageymium (PU) ndi Newdymium (Nǚ).

Pambuyo pake, akatswiri a zamankhwala padziko lonse lapansi adalandira chidwi kwambiri polekanitsa zinthu zatsopano zomwe adapeza padziko lapansi.

Mu 1885, avwelsbach, a ku Austria, adapeza zowonetsera ndi Ndenemmium ndi Newdmium kuchokera kusakanikirana wa prasedmium ndi Newdndmium yomwe yawerengedwa ndi MOSTnder ngati "zinthu zatsopano". M'modzi wa iwo dzina lake Newnmium, omwe pambuyo pake adakwaniritsidwa ku Newdymium. Chizindikiro cha ND ndi Ndentmium.

Newdymium, Prageymium, gadolinium (Gálinium (Gá) ndi Samarium (Shan) onse adasiyanitsidwa ndi DEYMMIum, yomwe idawerengedwa ngati gawo lamtsogolo nthawi imeneyo. Chifukwa cha zomwe apeza, disymium sasungidwanso. Ndikupeza kwawo kuti atsegule khomo lachitatu kuti atulutsidwe padziko lapansi, ndipo ndi gawo lachitatu la kupezeka kwa zinthu zachilengedwe padziko lapansi. Koma uyu ndi theka lokha la ntchito yomwe ili mu gawo lachitatu.Muko wa cerium uyenera kutsegulidwa kapena kupatukana kwa cerium kumalizidwa, ndipo theka linalo liyenera kutsegulidwa kapena kutsegulidwa kwa Y Fttrika.

Newdymium, mankhwala chizindikiro ndi zitsulo zoyera, ndi imodzi mwa zitsulo zogwira kwambiri zapadziko lapansi, ndikusungunuka kwa 1024 ° C - Chuma cha 7.004 g /㎝, ndi paramagnetism.

Akuluakulu AMENE:

Newdymium yakhala malo otentha pamsika kwa zaka zambiri chifukwa chokhala padera kumunda wa dziko lapansi. Wogwiritsa ntchito kwambiri ku Newdymium Media ndi NDFAB yamuyaya. Kubwera kwa maginito osatha a NDFF adagwira ntchito mwamphamvu kwambiri padziko lapansi. Maginito a NDFF amatchedwa "mfumu yazambiri zamagetsi" chifukwa cha mphamvu yamagetsi yokhazikika.

Newdymium imagwiritsidwanso ntchito pazida zosafanana. Kuonjezera 1.5-2.5% nedymium to Magnesium kapena aluminium aluya amatha kusintha kutentha kwambiri, mpweya wopondapo ndi kugwiritsidwa ntchito kwambiri ngati zida za Arospace.

Kuphatikiza apo, Newymium-dopydium-yttrium aluminium adyene amapanga mtengo wochepa, womwe umagwiritsidwa ntchito kwambiri powonjeza ndikudula zinthu zopyapyala ndi makulidwe pansi pa 10mmm.

Mu chithandizo chamankhwala, ND: Yag laser imagwiritsidwa ntchito pochotsa opaleshoni kapena mankhwalawa mankhwala m'malo mwa scalpel. Newdymium imagwiritsidwanso ntchito ngati galasi lokongoletsa komanso zinthu zadothi komanso monga zowonjezera pazinthu za mphira.

Ndi chitukuko cha sayansi ndi ukadaulo ndi kufalikira ndi kuwonjezera kwa sayansi yapadziko lapansi komanso ukadaulo, Newdymium idzakhala ndi malo okwanira.

Newdymium (ND) ndi chitsulo cham'dziko lapansi. Chikasu chachikasu, osavuta oxidized mlengalenga, omwe amagwiritsidwa ntchito popanga zigalasi ndi galasi lokhatha.

Kubadwa kwa Pragesoodmuum, Ninymium kunayamba kukhala. Kubwera ku Newdymium kunayambitsa munda wamoyo wanthawi zonse, kunathandiza kwambiri m'munda wachiwiri, ndipo anachititsa msika womwewo.

Kugwiritsa ntchito ku Newdymium: Zimagwiritsidwa ntchito popanga ceramics, galasi lofiirira lofiirira, ruby ​​yopanga mu laser ndi galasi yapadera yosefera khwangwala. Amagwiritsidwa ntchito limodzi ndi Pragesodymium kuti apangitse magalasi owomba magalasi. Zitsulo zachitsulo zomwe zimagwiritsidwa ntchito popanga zitsulo zomwe zimakhalanso ndi 18% Nentymium.

Nentymium oxide nd2 o3; Kulemera kwa maselo ndi 336.40; Lavender ufa wolimba, wosavuta kukhudzidwa ndi wonyowa, wotsekera mpweya dooxide mlengalenga, zokhutitsidwa m'madzi, sungunuka mu inorganic acid. Kuchulukitsa kwa anthu 7.24. Malo osungunuka ndi pafupifupi 1900 ℃, ndipo okwera kwambiri oxide wa ku Newdymium amatha kupangidwa pang'onopang'ono potenthedwa mlengalenga.

Kugwiritsa Ntchito: Ntchito zogwiritsidwa ntchito popanga maginito osatha

Nanozeter nedymium oxide amagwiritsidwanso ntchito ngati galasi lokongoletsa ndi zida zadothi, zinthu za mphira ndi zowonjezera.

Chitsulo cha pr-zd; Mawonekedwe a molecular ndi a Dr-ND; Katundu: siliva-imvi ya Inms Clocks, zachitsulo zosefukira, osavuta oxididrid mlengalenga. Cholinga: makamaka zogwiritsidwa ntchito ngati zida zamatsenga zosatha.

Chithandizo cha mankhwalawa chimakhala ndi mphamvu kwambiri m'maso ndi mucous nembanemba, kukwiya koyenera pakhungu, ndi inhalation kungayambitsenso embolory embolory ndi kuwonongeka kwa chiwindi.

Zochita:

Kukwiyitsa maso, khungu, mucous nembanemba komanso kupuma thirakiti.

Yankho:

1. Inhalation: Siyani malowa kuti muwapatse mpweya wabwino. Ngati kupuma kumakhala kovuta, perekani mpweya. Pitani kuchipatala.

2. Kulumikizana ndi maso: Kwezani eyelid ndikutsuka ndi madzi kapena mchere wamba. Pitani kuchipatala.

3. Kulumikizana ndi khungu: Chotsani zovala zoipitsidwa ndi kutsuka ndi madzi.

4. Kudya: Imwani madzi ambiri ofunda kuti agwetse kusanza. Pitani kuchipatala.
