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". I-Praseodymium ne-Neodymium isho ukuthi "amawele" ngesiGreki. Cishe eminyakeni engu-40 kamuva, okungukuthi, ngo-1885, lapho kusungulwa ingubo yesibani se-steam, i-Austrian Welsbach yahlukanisa ngempumelelo izakhi ezimbili ku-"praseodymium ne-neodymium", enye ebizwa ngokuthi "neodymium" kanti enye ibizwa ngokuthi "praseodymium". Lolu hlobo "lwewele" luhlukaniswe, futhi isici se-praseodymium sinezwe laso elikhulukazi lokubonisa amathalente ayo. I-Praseodymium iyisici somhlaba esingavamile esinenani elikhulu, elisetshenziswa engilazini, i-ceramics nezinto zikazibuthe.

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 ehlanzekile ye-neodymium 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 kusihlungi se-molecular ye-Y zeolite 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.
