Maombi ya oksidi ya Praseodymium
1:Oksidi ya Praseodymium, pia huitwa Praseodymia, hutumika kupaka rangi miwani na enameli;inapochanganywa na vifaa vingine, Praseodymium hutoa rangi ya manjano safi sana kwenye glasi.
2:Kipengele cha glasi ya didymium ambayo ni rangi ya miwani ya kuchomelea, pia kama nyongeza muhimu ya rangi ya manjano ya Praseodymium.
3:Oksidi ya Praseodymium katika myeyusho thabiti na ceria, au na ceria-zirconia, imetumika kama vichocheo vya oksidi.4:Inaweza kutumika kutengeneza sumaku zenye nguvu nyingi zinazojulikana kwa nguvu na uimara wao.
