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.The pigmenti mere bụ ìhè odo na-acha ọcha na mara agba.

(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 ya 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.
