Nezve Praseodymium
Praseodymium isiri nyore, silvery, malleable metal akazvipira kubva neodymium mu1885 na Welsbach kubva chii chaiva kufungidzirwa kuti 'didymium.'
Mashandisiro & Maapplication
Magetsi (ne neodymium), ndege injini, welder's goggles, uye ceramics colorant.
Nhoroondo yemitambo
Praseodymium yaive yakachengetwa kwemakore akawanda mukati 'didymium' kusvika pakupedzisira yaive yakabatana ne neodymium mu1885.
