Praseymium (III, IV) oxide
Praseymium (III, IV) oxideKodi ndi mankhwala ochulukirapo ndi formula Playo11 yomwe ili yopanda madzi. Ili ndi mawonekedwe a chimfine. Ndiwo mawonekedwe okhazikika kwambiri a prageymium oxide pa kutentha kwa mawonekedwe a kozungulira ndikupanikizika. Prageymium (III, IV) oxide nthawi zambiri imakhala yoyera (99.99) Praseymium (III, IV) ufa wopezeka mosachedwa. Ultra zoyera kwambiri komanso mawonekedwe okwanira oyekula bwino zabwino ndi zothandiza monga mfundo za sayansi. Nanoscale woyamba ufa ndi kuyimitsidwa, ngati mitundu ina yapamwamba, ikhoza kuganiziridwa.
