I-Needymium ingenye yezinsimbi zomhlaba ezisebenzayo kakhulu zomhlaba

Ngo-1839, iSweden CGmosander yathola ingxube yeLanthanum (Lan) ne-PraceOdDodymium (PU) neNeodymium (Nǚ).

Emva kwalokho, osokhemisi emhlabeni wonke banaka ngokukhethekile ukwahlukanisa izinto ezintsha abathola izinto zomhlaba ezingandile.

Ngo-1885, avwelsbach, i-Austrian, ethola i-PraceDoymium neNeodymium kusuka kwingxube ye-PraceOdDodymium neNeodmium ebhekwe yi-mossander njenge "izinto ezintsha". Omunye wabo waqanjwa ngokuthi yi-neodymium, eyayiselula kamuva ne-neodymium. Isibonakaliso ND yiNeodymium.

I-Neodymium, i-PraceOdDedmium, Gadinimium (Gá) neSamarium (Shan) yonke yahlukaniswa ne-Didymium, eyayithathwa njengento evamile yomhlaba ngaleso sikhathi. Ngenxa yokutholwa kwabo, i-hadymium ayisagciniwe. Kukuthola kwabo okuvula umnyango wesithathu kokutholakele kwezinto zomhlaba ezingandile futhi kuyisigaba sesithathu sokutholwa kwezinto zomhlaba ezingavamile. Kepha lokhu kuyingxenye yomsebenzi kuphela esigabeni sesithathu.ExActly, isango le-cereyumu kufanele livulwe noma ukwahlukaniswa kwe-cerium kuqediwe, kanti enye ingxenye kufanele ivulwe noma uhlukaniswe ngenye ingxenye ye-yttrium.

NeNeodmium, uphawu lwamakhemikhali i-ND, i-Silvery White Metal, ingenye yezinsimbi zomhlaba ezingandile kakhulu zomhlaba, ngephuzu elincibilikayo le-1024 ° C, Ubuningi be-724 g /㎝, ne-paramagnetism.

Ukusetshenziswa okuyinhloko:

I-Needymium isibe yindawo eshisayo emakethe iminyaka eminingi ngenxa yesikhundla sayo esiyingqayizivele emkhakheni wabantu abangafani. Umsebenzisi omkhulu kakhulu we-Neodymium Metal yi-NDFEB unomphela wezinto zozibuthe. Ukuqala kwe-NDFEB Magnets unomphela kufakwe ubuhlakani obusha bube yinkambu ye-Rare Emhlabeni Ephakeme. I-NDFEB uzibuthe ibizwa ngokuthi "inkosi yama-magnets anaphakade" ngenxa yomkhiqizo wayo ophakeme wamandla kazibuthe.Kusetshenziswa kabanzi kuma-elekthronikhi, imishini kanye nezinye izimboni ngokusebenza kwayo okuhle.

I-Neodymium nayo isetshenziswa ezintweni ezingezona ze-Ferrous. Ukungeza i-1.5-2.5% neodymium ku-Magnesium noma i-Aluminium Alloy kungathuthukisa ukusebenza okuphezulu okuphezulu, ukuqina komoya nokuphikiswa kokugqwala kwe-alloy, futhi kusetshenziswa kabanzi njengezinto zokulungiswa kwe-aerospace.

Ngaphezu kwalokho, i-neodymium-doped ytttrium aluminium garonet ikhiqiza ugongolo lwe-waser olufushane lwe-waser, olusetshenziswa kabanzi ekushiseni nasekunciphiseni izinto ezincanyana ezinobukhulu ngaphansi kwe-10mm embonini.

Kwezokwelapha, ND: I-Yag Laser isetshenziselwa ukususa ukuhlinzwa noma amagciwane amanxeba esikhundleni se-scalpel. I-Needmium nayo isetshenziselwa imibala yezinto zokwenza imibala kanye nezinto zokwakha i-ceramic kanye nesengezo semikhiqizo yenjoloba.

Ngokuthuthukiswa kwesayensi nobuchwepheshe kanye nokwanda nokwandiswa kweRare Earth Science neTekhnoloji, iNeodymium izoba nendawo ebanzi yokusebenzisa.

I-Neodymium (ND) iyinsimbi evamile emhlabeni. Uphuzi ophuzi, ocwebezelwe kalula emoyeni, esetshenziselwa ukwenza i-alloy nengilazi ye-aptical.

Ngokuzalwa kwePrafeDodymium, uNeodymium waba khona. Ukufika kweNeodyimu kusebenze i-Rare Earth Field, badlale indima ebalulekile ensimini yaseMhlabeni eyiRare, futhi bathonya imakethe yomhlaba engavamile.

Ukusetshenziswa kweNeodymium: Kusetshenziselwa ukwenza i-ceramics, ingilazi ebubende ekhanyayo, i-ruby yokufakelwa e-laser nengilazi ekhethekile ekwazi ukuhlunga imisebe ye-infrared infrared. Kusetshenziswe kanye ne-PraceOdymium ukwenza ama-goggles ama-cloowers engilazi. I-Mic Metal esetshenzisiwe e-Steelmaking ibuye iqukethe i-18% neodymium.

Neodymium oxide ND2 O3; Isisindo samangqamuzana singama-336.40; I-Lavender Solid Powder, Easy to Founday nge-DAMP, edonsa i-carbon dioxide emoyeni, insoluble emanzini, incibilike ku-inorganic acid. Ubuningi obuhlobene ngu-7.24. Iphuzu lokuncibilika licishe libe ngu-1900 ℃, futhi i-valence avance oxide yeNeodymium ingakhiwa ngokwengxenye ngokushisa emoyeni.

Isebenzisa: Isetshenziselwa ukwenza izinto zozibuthe ezingapheli, imibala yengilazi nama-ceramics nezinto zokwakha ama-laser.

I-Nanometer Neodymium oody futhi isetshenziselwa imibala yengilazi nezinto zokwakha ubumba, imikhiqizo yenjoloba kanye nezithasiselo.

I-Pr-ND Metal; Ifomula yama-molecular i-PR-ND; Izakhiwo: Isiliva-Grey Metallic block, i-nsimbi ye-luster, efakwe kalula emoyeni. INJONGO: Ngokuyinhloko esetshenziswa njengezinto zozibuthe ezingapheli.

I-PreferNeodymium enokucasulwa okunamandla ngamehlo kanye nolwelwesi lwe-mucous, ukucasuka ngokulinganiselayo esikhunjeni, futhi ukuphefumula nakho kungadala ukuphambuka kwamaphaphu nokulimala kwesibindi.

Into Yesenzo:

Ukucasula amehlo, isikhumba, ulwelwesi lwe-mucous kanye nepheshana lokuphefumula.

Isixazululo:

1. Ukuphefumula: shiya isiza emoyeni omusha. Uma ukuphefumula kunzima, nikeza umoya-mpilo. Funa ukunakekelwa kwezokwelashwa.

2. Ukuxhumana ngamehlo: Phakamisa ijwabu leso bese hlambulula ngamanzi agijimayo noma usawoti ojwayelekile. Funa ukunakekelwa kwezokwelashwa.

3. Ukuxhumana kwesikhumba: Susa izingubo ezingcolile futhi hlambulula ngamanzi agobhozayo.

4. Ukudla: Phuza amanzi amaningi afudumele ukunxenxa ukugabha. Funa ukunakekelwa kwezokwelashwa.
