Gukoresha ibintu bidasanzwe byisi Praseodymium (pr).

Praseodymium (Pr) Hafi yimyaka 160 ishize, Suwede Mosander yavumbuye ikintu gishya kiva muri lanthanum, ariko ntabwo arikintu kimwe. Mosander yasanze imiterere yiki kintu isa cyane na lanthanum, ayita “Pr-Nd”. “Praseodymium na Neodymium” bisobanura “impanga” mu kigereki. Nyuma yimyaka igera kuri 40, ni ukuvuga, mu 1885, igihe havumbuwe umwenda wamatara wamazi, umunya Otirishiya Welsbach yatandukanije neza ibintu bibiri na "praseodymium na neodymium", kimwe cyitwa "neodymium" ikindi cyitwa "praseodymium". Ubu bwoko bw "impanga" buratandukanye, kandi praseodymium ifite isi nini yo kwerekana impano zayo. Praseodymium nikintu kidasanzwe cyubutaka gifite ubwinshi, bukoreshwa mubirahure, ububumbyi nibikoresho bya magneti.

praseodymium (Pr)

Praseodymium umuhondo (kuri glaze) atome itukura (kuri glaze).

Pr-Nd

praseodymium oxyde

Praseodymium neodymium fluoride

Ikoreshwa ryinshi rya praseodymium:

(1) Praseodymium ikoreshwa cyane mukubaka ububumbyi nubukorikori bwa buri munsi. Irashobora kuvangwa na ceramic glaze kugirango ikore ibara ryamabara, kandi irashobora no gukoreshwa nka pigment yumuriro wenyine. Ibara ryakozwe ni umuhondo wijimye ufite ibara ryiza kandi ryiza.

(2) Ikoreshwa mugukora magnesi zihoraho. Guhitamo icyuma cya praseodymium na neodymium aho kuba icyuma cya neodymium cyiza kugirango gikore ibintu bya magneti bihoraho birashobora kunoza imyuka ya ogisijeni hamwe nubukanishi, kandi birashobora gutunganyirizwa mumaseti yuburyo butandukanye. Byakoreshejwe cyane mubikoresho bya elegitoroniki na moteri zitandukanye.

(3) kubikomoka kuri peteroli. Ongeramo praseodymium ikungahaye hamwe na neodymium mumashanyarazi ya Y zeolite kugirango utegure catalizeri yameneka irashobora kunoza ibikorwa, guhitamo no gutuza kwa catalizator. Ubushinwa bwatangiye gukoresha inganda mu myaka ya za 70, kandi ibyo bukoresha biriyongera.

(4) Praseodymium irashobora kandi gukoreshwa mugukata neza. Mubyongeyeho, praseodymium ikoreshwa cyane mubijyanye na fibre optique.
