Kushandiswa kweisingawanzo pasi chinhu Praseodymium (pr).

Praseodymium (Pr) Makore angangoita 160 apfuura, Mosander wekuSweden akawana chinhu chitsva kubva ku lanthanum, asi hachisi chinhu chimwe chete. Mosander akaona kuti chimiro chechinhu ichi chakafanana nelanthanum, ndokuchitumidza kuti "Pr-Nd". "Praseodymium uye Neodymium" zvinoreva "mapatya" muchiGiriki. Anenge makore makumi mana gare gare, ndiko kuti, muna 1885, pakatangwa chigadziko chemwenje, Welsbach weAustria akabudirira kupatsanura zvinhu zviviri kubva ku "praseodymium neodymium", imwe inonzi "neodymium" uye imwe inonzi "praseodymium". Rudzi urwu rwe "mapatya" rwakaparadzaniswa, uye chinhu chepraseodymium chine nyika yayo yakakura kuratidza matarenda ayo. Praseodymium chinhu chisingawanzo pasi pasi chine huwandu hukuru, chinoshandiswa mugirazi, ceramics uye magineti zvinhu.

praseodymium (Pr)

Praseodymium yero (ye glaze) atomic tsvuku (ye glaze).

Pr-Nd chiwanikwa

praseodymium oxide

Praseodymium neodymium fluoride

Kushandiswa kwakakura kwepraseodymium:

(1) Praseodymium inoshandiswa zvakanyanya mukuvaka makeramics uye mazuva ese-kushandisa ceramics. Inogona kusanganiswa neceramic glaze kugadzira glaze yemavara, uye inogona kushandiswa se underglaze pigment chete. Iyo pigment yakagadzirwa ndeyero yero uye yakachena uye inoyevedza ruvara.

(2) Inoshandiswa kugadzira magineti echigarire. Kusarudza yakachipa praseodymium uye neodymium simbi panzvimbo yakachena neodymium simbi kugadzira zvechigarire magineti zvinhu zvinogona zviri pachena kuvandudza ayo okisijeni kuramba uye michina zvivakwa, uye anogona kugadziriswa magineti akasiyana maumbirwo. Inoshandiswa zvakanyanya mumhando dzakasiyana dzemagetsi uye mota.

(3) ye petroleum catalytic cracking. Kuwedzera yakafumiswa praseodymium uye neodymium muY zeolite molecular sieve kugadzirira petroleum cracking catalyst inogona kuvandudza chiitiko, kusarudzwa uye kugadzikana kweiyo catalyst. China yakatanga kuisa mukushandiswa kwemaindasitiri muma1970, uye kushandiswa kwayo kuri kuwedzera.

(4) Praseodymium inogona zvakare kushandiswa pakupusha abrasive. Mukuwedzera, praseodymium inoshandiswa zvakanyanya mumunda we optical fiber.
