Iarrtas:
Bhiodh Praseodymium Oxide, ris an canar cuideachd Praseodymia, air a chleachdadh airson glainneachan agus cruain a dhath;nuair a thèid a mheasgachadh le stuthan sònraichte eile, bidh Praseodymium a’ toirt a-mach dath buidhe glan ann an glainne.Co-phàirt de ghlainne didymium a tha na dhath airson goggles welder, cuideachd mar chur-ris cudromach de dhath buidhe Praseodymium.Chaidh praseodymium oxide ann am fuasgladh cruaidh le ceria, no le ceria-zirconia, a chleachdadh mar chatalan oxidation.Faodar a chleachdadh gus magnets àrd-chumhachd a chruthachadh a tha sònraichte airson an neart agus an seasmhachd.
