Kushandisa kweRare Pasi Element praseodymium (PR).

Praseodymium (PR) anenge makore gumi nematanhatu apfuura, Sweden mosander akawana chinhu chitsva kubva kuna Lanthanamu, asi hachisi chinhu chimwe chete. Mosanander akawana kuti chimiro chechinhu ichi chakafanana chaizvo neLanthanum, uye zita rinonzi "Prwen nd". "Praseodymium uye neodymium" zvinoreva "mapatya" muchiGiriki. Anenge makore makumi mana gare gare, uyo ari muna 1885, apo The Steam Lamp Yakatangwa, Austrian Welsbach zvakabudirira kubva ku "Praseodymium Rudzi urwu rwe "Twin" rwakaparadzaniswa, uye chinhu chePraseodymium chine nyika yayo yakazara kuratidza matarenda ayo. Praseodymium chinhu chisingawanzo kuitika pasi neyakaenzana, iyo inoshandiswa mugirazi, ceramics uye magineti zvinhu.

Iyo yakafara application ye praseodymium:

(1) Praseodymium inoshandiswa zvakanyanya mukuvaka ceramics uye zuva nezuva-kushandisa ceramics. Inogona kusanganiswa ne ceramic glaze kuti iite glazy glaze, uye inogona zvakare kushandiswa seyakagadziriswa pigment ega. Iyo pigment yakagadzirwa iine mwenje yero ine yakachena uye yakajeka mavara.

(2) inoshandiswa kugadzira magneti zvachose. Kusarudza zvakachipa. Inoshandiswa zvakanyanya mumidziyo yakasiyana-siyana yemagetsi uye motors.

(3) ye peturuleum catalytic kupaza. Kuwedzera yakarukwa praseodymium uye neodymium muY zeolite molecular sosi yekugadzirira petroleum cracking crallyst inogona kuvandudza chiitiko, kusarudza uye kugadzikana kweiyo catalyst. China yakatanga kuisa mukushandiswa kwemaindasitiri muma1970s, uye kushandiswa kwayo kuri kuwedzera.

(4) Praseodymium inogonawo kushandiswa kukanganisa kupukuta. Mukuwedzera, praseodymium inoshandiswa zvakanyanya mumunda weye Optical fiber.
