Ngwa:
Praseodymium Oxide, nke a na-akpọkwa Praseodymia, na-eji agba ugogbe anya na enamels; mgbe agwakọtara ya na ụfọdụ ihe ndị ọzọ, Praseodymium na-emepụta agba odo dị ọcha nke ukwuu n'ime iko. Akụkụ nke iko didymium nke bụ agba maka enyo welder, dịkwa ka ihe mgbakwunye dị mkpa nke Praseodymium odo pigmenti. Praseodymium Oxide na ngwọta siri ike nwere ceria, ma ọ bụ ya na ceria-zirconia, ejirila ya mee ihe dị ka ihe na-akpali akpali oxidation. Enwere ike iji ya mepụta ihe ndọta dị elu ama ama maka ike na ịdịte aka ha.
