Za ine Praseodymium
Praseodymium ndi wolimba, silvery, maonekedwe amtundu wa miyala yosiyana ndi neodymium mu 1885 ndi Welsbach kuchokera pa zomwe zinaganiziridwa kuti ndi 'didymium.'
Kugwiritsa ntchito & Maphunziro
Ma magnets (ndi neodymium), injini za ndege, zovala za welder, ndi zokongoletsa za ceramics.
Fun Facts
Praseodymium anali kuikidwa kwa zaka zingapo m'ma 'didymium' mpaka pamene pamapeto pake anatenga kuchokera ku neodymium mu 1885.
