Iarrtas Oxide plaseredysmium
1: paséodymium paseide, ris an canar passeysedmia, air a chleachdadh gus glainneachan is cruan-starra a làimhseachadh; Nuair a bhios tu air a mheasgachadh le stuthan sònraichte eile, bidh paséisemium a 'dèanamh dath mòr le dian glan ann an glainne.
2: Pàirt de ghlainne dédymium a tha na cholobhan airson goggles welder, cuideachd mar phearaman buidhe passeeosicumium.
3: Chaidh paséisemium oxide ann am fuasgladh cruaidh le Ceria, no le Ceria-Zirconia, a chleachdadh mar oxitations gu leòr. 4: faodar a chleachdadh gus magnets àrd-chumhachd a chruthachadh gu sònraichte airson an neart agus seasmhachd.
