Ukusetyenziswa kwento enqabileyo yomhlaba iPraseodymium (pr).

I-Praseodymium (Pr) Malunga neminyaka eyi-160 eyadlulayo, i-Swedish Mosander yafumanisa into entsha kwi-lanthanum, kodwa ayiyonto enye.U-Mosander wafumanisa ukuba uhlobo lwale elementi lufana kakhulu ne-lanthanum, kwaye lwabiza igama elithi "Pr-Nd"."Praseodymium kunye neodymium" lithetha "amawele" ngesiGrike.Malunga neminyaka engama-40 kamva, oko kukuthi, ngowe-1885, xa kwaveliswa ingubo yesibane somphunga, i-Austrian Welsbach yahlula ngempumelelo izinto ezimbini kwi "praseodymium kunye neodymium", enye ebizwa ngokuba yi "neodymium" kunye nenye ebizwa ngokuba yi "praseodymium".Olu hlobo "lwewele" lwahluliwe, kwaye i-praseodymium element inehlabathi layo elikhulu lokubonisa iitalente zayo.I-Praseodymium yinto enqabileyo yomhlaba enexabiso elikhulu, elisetyenziswa kwiglasi, iikeramics kunye nezinto eziphathekayo.

ipraseodymium (Pr)

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

Ingxubevange yePr-Nd

i-praseodymium oxide

Praseodymium neodymium fluoride

Ukusetyenziswa okubanzi kwepraseodymium:

(1) I-Praseodymium isetyenziswa ngokubanzi kwi-ceramics yokwakha kunye ne-ceramics yokusetyenziswa kwansuku zonke.Inokuxutywa ne-ceramic glaze ukwenza i-glaze enemibala, kwaye ingasetyenziselwa njenge-pigment engaphantsi kwe-pigment yodwa.I-pigment eyenziwe yi-pigment ekhanyayo kunye nombala ococekileyo kunye nobuhle.

(2) Isetyenziselwa ukwenza iimagnethi ezisisigxina.Ukukhetha i-praseodymium enexabiso eliphantsi kunye ne-neodymium yesinyithi endaweni yentsimbi ecocekileyo ye-neodymium ukwenza imathiriyeli yemagnethi esisigxina ngokuqinisekileyo inokuphucula ukuxhathisa kweoksijini kunye neempawu zoomatshini, kwaye inokusetyenzwa ibe ziimagnethi zeemilo ezahlukeneyo.Isetyenziswa ngokubanzi kwizixhobo ezahlukeneyo zombane kunye neenjini.

(3) kwipetroleum catalytic cracking.Ukongeza i-praseodymium ephuculweyo kunye neodymium kwi-Y zeolite i-molecular sieve ukulungiselela i-petroleum cracking catalyst inokuphucula umsebenzi, ukukhetha kunye nokuzinza kwe-catalyst.I-China yaqala ukufaka ukusetyenziswa kwezoshishino kwi-1970s, kwaye ukusetyenziswa kwayo kuyanda.

(4) I-Praseodymium nayo ingasetyenziselwa ukugulisa i-abrasive.Ukongezelela, i-praseodymium isetyenziswa ngokubanzi kwintsimi ye-fiber optical.
