Maombi ya oksidi ya praseodymium
1: praseodymium oxide, pia huitwa praseodymia, iliyotumiwa kuchora glasi na enamels; Wakati inachanganywa na vifaa vingine, praseodymium hutoa rangi safi ya manjano katika glasi.
2: Sehemu ya glasi ya didymium ambayo ni rangi ya miiko ya Welder, pia kama nyongeza muhimu ya rangi ya manjano ya praseodymium.
3: Praseodymium oksidi katika suluhisho thabiti na ceria, au na ceria-zirconia, zimetumika kama vichocheo vya oxidation. 4: Inaweza kutumika kuunda sumaku zenye nguvu za juu zinazojulikana kwa nguvu na uimara wao.
