Ukusetshenziswa kwento engavamile yomhlaba i-Praseodymium (pr).

I-Praseodymium (Pr) Cishe eminyakeni engu-160 edlule, i-Swedish Mosander yathola into entsha evela ku-lanthanum, kodwa akuyona into eyodwa.U-Mosander uthole ukuthi imvelo yalesi sici ifana kakhulu ne-lanthanum, futhi wayiqamba ngokuthi "Pr-Nd".Igama elithi "Praseodymium ne-Neodymium" lisho "amawele" ngesiGreki.Cishe eminyakeni engu-40 kamuva, okungukuthi, ngo-1885, lapho kusungulwa ingubo yesibani se-steam, u-Welsbach wase-Austrian wahlukanisa ngempumelelo izakhi ezimbili ku-"praseodymium neodymium", enye ebizwa ngokuthi "neodymium" kanti enye ibizwa ngokuthi "praseodymium".Lolu hlobo "lwewele" luhlukanisiwe, futhi isici se-praseodymium sinomhlaba wayo omkhulu wokubonisa amathalente ayo.I-Praseodymium iyisici somhlaba esingavamile esinenani elikhulu, elisetshenziswa engilazini, i-ceramics nezinto zikazibuthe.

i-praseodymium (Pr)

I-Praseodymium ephuzi (ye-glaze) ebomvu ye-athomu (ye-glaze).

Ingxubevange ye-Pr-Nd

i-praseodymium oxide

I-Praseodymium neodymium fluoride

Ukusetshenziswa okubanzi kwe-praseodymium:

(1) I-Praseodymium isetshenziswa kakhulu ekwakheni izitsha zobumba nezisetshenziswa nsuku zonke.Ingaxutshwa ne-ceramic glaze ukwenza i-glaze enemibala, futhi ingasetshenziswa njenge-pigment engaphansi kwe-underglaze yodwa.I-pigment eyenziwe iphuzi ngokukhanyayo nombala omsulwa futhi omuhle.

(2) Isetshenziselwa ukukhiqiza omazibuthe baphakade.Ukukhetha i-praseodymium eshibhile nensimbi ye-neodymium esikhundleni sensimbi ye-neodymium ehlanzekile ukwenza izinto zikazibuthe unomphela kungathuthukisa ukumelana komoya-mpilo kanye nezakhiwo zemishini, futhi kungacutshungulwa kube omazibuthe bezinhlobo ezihlukahlukene.Isetshenziswa kabanzi kumadivaysi e-elekthronikhi namamotho ahlukahlukene.

(3) ukuqhekeka kwe-petroleum catalytic.Ukwengeza i-praseodymium ecebile ne-neodymium ku-Y zeolite ye-molecular sieve ukuze kulungiswe i-petroleum cracking catalyst kungathuthukisa umsebenzi, ukukhetha nokuzinza kwe-catalyst.I-China yaqala ukusetshenziswa ezimbonini ngawo-1970, futhi ukusetshenziswa kwayo kuyanda.

(4) I-Praseodymium ingabuye isetshenziselwe ukupholishwa okugaqayo.Ngaphezu kwalokho, i-praseodymium isetshenziswa kabanzi emkhakheni we-fiber optical.
