Ngwa nke ihe mejupụtara ụwa na-adịghị ahụkebe Praseodymium (pr).

Praseodymium (Pr) Ihe dị ka afọ 160 gara aga, Swedish Mosander chọpụtara ihe ọhụrụ sitere na lanthanum, mana ọ bụghị otu ihe. Mosander chọpụtara na ọdịdị nke mmewere a yiri lanthanum, wee kpọọ ya "Pr-Nd". "Praseodymium na Neodymium" pụtara "ejima" na Grik. Ihe dị ka afọ 40 ka e mesịrị, ya bụ, na 1885, mgbe e mepụtara uwe mwụda uzuoku, Australia Welsbach nke ọma kewapụrụ ihe abụọ na "praseodymium na neodymium", otu aha ya bụ "neodymium" na nke ọzọ aha ya bụ "praseodymium". Ụdị "ejima" a na-ekewa, na praseodymium element nwere nnukwu ụwa nke ya iji gosipụta talent ya. Praseodymium bụ ihe na-adịghị ahụkebe nke ụwa nwere nnukwu ego, nke a na-eji na iko, ceramik na ihe ndọta.

Ngwa ngwa nke praseodymium:

(1) A na-eji Praseodymium eme ihe n'ọtụtụ ebe n'ịrụ ceramik na seramiki a na-eji kwa ụbọchị. Enwere ike ịgwakọta ya na glaze seramiiki iji mee glaze nwere agba, a pụkwara iji ya dị ka pigmenti n'okpuru glaze naanị. Nri a na-eme bụ odo odo na-acha ọcha ma mara mma.

(2) Eji maka imepụta magnetik na-adịgide adịgide. Ịhọrọ praseodymium na neodymium metal dị ọnụ ala kama ịbụ ọla neodymium dị ọcha iji rụpụta ihe ndọta na-adịgide adịgide nwere ike imeziwanye nguzogide oxygen na akụrụngwa akụrụngwa, enwere ike ịhazi ya ka ọ bụrụ ndọta nke ụdị dị iche iche. A na-eji ya na ngwaọrụ eletrọnịkị dị iche iche na moto.

(3) maka petroleum catalytic cracking. Ịtinye praseodymium na neodymium bara ụba n'ime Y zeolite molecular sieve iji dozie ihe na-eme ka mmanụ ala nwee ike imeziwanye ọrụ, nhọrọ na nkwụsi ike nke ihe mkpali. China malitere itinye n'ọrụ mmepụta ihe na 1970s, oriri ya na-abawanye.

(4) Enwere ike iji Praseodymium mee ihe maka nchacha abrasive. Na mgbakwunye, a na-eji praseodymium eme ihe n'ọhịa nke eriri anya.
