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, ngo-1885, xa kwaveliswa ingubo yesibane somphunga, i-Austrian Welsbach yahlula ngempumelelo izinto ezimbini kwi "praseodymium kunye neodymium", enye ebizwa ngokuba yi "neodymium" kwaye enye ibizwa 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.

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 ukubeka 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.
