    Praseodymium(III,IV) Oxide

    Praseodymium (III, IV) Oxidendi organic pawiri ndi chilinganizo Pr6O11 amene sasungunuke m'madzi. Ili ndi mawonekedwe a cubic fluorite. Ndiwokhazikika kwambiri wa praseodymium oxide pa kutentha kozungulira ndi pressure.It ndi gwero la Praseodymium losasunthika kwambiri la thermally loyenera magalasi, optic ndi ceramic applications. Praseodymium(III,IV) Oxide nthawi zambiri imakhala Yoyera Kwambiri (99.999%) Praseodymium(III,IV) Oxide (Pr2O3) Powder yomwe ikupezeka posachedwa m'mavoliyumu ambiri. Zolemba zoyera kwambiri komanso zoyera kwambiri zimakweza mawonekedwe komanso zothandiza ngati miyezo yasayansi. Nanoscale elemental powders ndi suspensions, monga njira zina zamtunda wapamwamba, zitha kuganiziridwa.
