Kugwiritsa ntchito nyama yaikazi yaikulu ya pragesonmium (pr).

Prageymium (PR) Pafupifupi zaka 160 zapitazo, a Nandedish adanda adapeza chinthu chatsopano kuchokera ku Lantanam, koma sichinthu chimodzi. Mosander anazindikira kuti mtundu wa chinthu ichi ndi wofanana kwambiri ndi Lanthanam, ndipo anautcha kuti "pr-ng". "Praseodmium ndi Newdymium" amatanthauza "mapasa" m'Chigiriki. Pafupifupi zaka 40 pambuyo pake, ndiye kuti, mu 1885, pamene nyali ya Stean idapangidwa mozama kuchokera ku "Praseydium ndi Newddium", wina wotchedwa "Praoneodymium". "Tsan" ya "Twin" imalekanitsidwa, ndipo chinthu choyambirira cha Pragegeymium chili ndi dziko lake lalikulu kuti liwonetsetse maluso ake. Praceodymium ndi gawo loipa kwambiri padziko lapansi lokhala ndi ndalama zambiri, zomwe zimagwiritsidwa ntchito mugalasi, ma simeramic ndi zida.

Praseymium (pr)

Prageymium yachikasu (ya glaze) atomiki ofiira (glaze).

Pr-nd alloy

Prageymium oxide

Prageedymium Newdymium Fluoride

Kugwiritsa ntchito kwa Pragesodymium:

(1) Praseymium imagwiritsidwa ntchito kwambiri pomanga ma ceramics komanso kugwiritsa ntchito tsiku ndi tsiku. Itha kusakanikirana ndi ceraction glaze kuti ipange utoto wokongola, ndipo imatha kugwiritsidwanso ntchito ngati pigment yotsika yokha. Ma pigment omwe amapangidwa ndi chikasu chachikaso ndi upangiri woyera komanso wokongola.

(2) Kugwiritsidwa ntchito popanga maginito osatha. Kusankha zotsika mtengo ndi newdymium zitsulo m'malo mwa zitsulo zoyera kupanga maginito a Nentymium kuti zitheke ndi kupewetsa matenda ake, ndipo imatha kukonzedwa m'mapazi osiyanasiyana. Kugwiritsidwa ntchito kwambiri m'magawo osiyanasiyana amagetsi.

(3) ya petroleum catalytic. Kuonjezera zopanduka za Pragesodymium yolemedwa ndi nedymium mu y zeolite maelecular kuti mukonze zothandizira, kusadetsa ndi kukhazikika kwa chothandizira. China idayamba kuyika mu mafakitale mu 1970s, ndipo kumwa kwake kukukulira.

(4) Prasewymium itha kugwiritsidwanso ntchito popukusira. Kuphatikiza apo, Praseodymium imagwiritsidwa ntchito kwambiri m'munda wa fiber.
