Iarrtas praseodymium oxide
1: Praseodymium Oxide, ris an canar cuideachd Praseodymia, air a chleachdadh airson glainneachan agus cruan a dhath;nuair a thèid a mheasgachadh le cuid de stuthan eile, bidh Praseodymium a’ toirt a-mach dath buidhe fìor-ghlan ann an glainne.
2: Co-phàirt de ghlainne didymium a tha na dhath airson goggles welder, cuideachd mar chur-ris cudromach de pigmentan buidhe Praseodymium.
3: Praseodymium Oxide ann am fuasgladh cruaidh le ceria, no le ceria-zirconia, air a bhith air a chleachdadh mar catalysts oxidation.4: Faodar a chleachdadh gus magnets àrd-chumhachd a chruthachadh a tha sònraichte airson an neart agus an seasmhachd.
