Kugwiritsa ntchito chinthu chosowa padziko lapansi Praseodymium (pr).

Praseodymium (Pr) Pafupifupi zaka 160 zapitazo, Mosander waku Sweden adapeza chinthu chatsopano kuchokera ku lanthanum, koma si chinthu chimodzi. Mosander adapeza kuti chikhalidwe cha chinthu ichi ndi chofanana kwambiri ndi lanthanum, ndipo adachitcha "Pr-Nd". "Praseodymium ndi Neodymium" amatanthauza "mapasa" mu Greek. Pafupifupi zaka 40 pambuyo pake, ndiye kuti, mu 1885, pamene chobvala cha nyali cha nthunzi chinapangidwa, Welsbach wa ku Austrian Welsbach adasiyanitsa bwino zinthu ziwiri kuchokera ku "praseodymium ndi neodymium", imodzi yotchedwa "neodymium" ndipo ina yotchedwa "praseodymium". "Amapasa" amtunduwu amalekanitsidwa, ndipo chinthu cha praseodymium chili ndi dziko lake lalikulu lowonetsera maluso ake. Praseodymium ndi chinthu chosowa padziko lapansi chokhala ndi kuchuluka kwakukulu, komwe kumagwiritsidwa ntchito mu galasi, zoumba ndi maginito.

praseodymium (Pr)

Praseodymium yellow (ya glaze) wofiira wa atomiki (wa glaze).

Kugwiritsa ntchito kwambiri praseodymium:

(1) Praseodymium imagwiritsidwa ntchito kwambiri pomanga ziwiya zadothi ndi zoumba zomwe zimagwiritsidwa ntchito tsiku ndi tsiku. Ikhoza kusakanikirana ndi glaze ya ceramic kuti ipange glaze yamitundu, komanso ingagwiritsidwe ntchito ngati pigment ya underglaze yokha. Pigment yopangidwa ndi yopepuka yachikasu ndi mtundu woyera komanso wokongola.

(2) Amagwiritsidwa ntchito popanga maginito okhazikika. Kusankha zitsulo zotsika mtengo za praseodymium ndi neodymium m'malo mwa zitsulo zoyera za neodymium kupanga zinthu zamaginito okhazikika zimatha mwachiwonekere kusintha kukana kwake kwa okosijeni ndi zinthu zamakina, ndipo zimatha kusinthidwa kukhala maginito amitundu yosiyanasiyana. Amagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamagetsi ndi ma mota.

(3) kuphwanya mafuta a petroleum. Kuonjezera praseodymium yowonjezeredwa ndi neodymium mu Y zeolite molekyulu sieve kukonzekera chothandizira kusweka kwa petroleum kumatha kupititsa patsogolo ntchito, kusankha komanso kukhazikika kwa chothandizira. China idayamba kugwiritsidwa ntchito m'mafakitale m'ma 1970, ndipo kugwiritsidwa ntchito kwake kukuchulukirachulukira.

(4) Praseodymium itha kugwiritsidwanso ntchito popukutira abrasive. Kuphatikiza apo, praseodymium imagwiritsidwa ntchito kwambiri pankhani ya kuwala kwa fiber.
