    I-Praseodymium(III,IV) Oxide

    I-Praseodymium (III,IV) Oxideiyinhlanganisela ye-inorganic enefomula ethi Pr6O11 engancibiliki emanzini. Inesakhiwo se-cubic fluorite. Iyindlela ezinzile kakhulu ye-praseodymium oxide ekushiseni okuzungezile kanye nokucindezela.Iwumthombo we-Praseodymium ongancibiliki kakhulu ngokushisa ofanele ingilazi, i-optic kanye ne-ceramic application. I-Praseodymium(III,IV) I-Oxide ivamise ukuhlanzeka Okuphezulu (99.999%) I-Praseodymium(III,IV) Oxide (Pr2O3) Powder etholakala kamuva nje ngamavolumu amaningi. Izingoma zokuhlanzeka okuphezulu nokuhlanzeka okuphezulu zithuthukisa ikhwalithi yokubona nokuba wusizo njengamazinga esayensi. Ama-Nanoscale elemental powders kanye nokumiswa, njengamanye amafomu wendawo ephezulu, angacatshangelwa.
