    Praseodymium(III,IV) oxide

    Praseodymium (III,IV) oxidewaa isku-dhafka aan organic ee leh caanaha Pr6O11 ee aan biyo ku milmin. Waxay leedahay qaab-dhismeedka fluorite cubic. Waa qaabka ugu xasiloon ee praseodymium oxide heerkulka deegaanka iyo cadaadiska.Waa il Praseodymium kuleyl ahaan aad u aan milmi karin oo ku habboon codsiyada muraayadaha, indhaha iyo dhoobada. Praseodymium(III,IV) Oksaydhku guud ahaan waa daahir sare (99.999%) Praseodymium(III,IV) Oxide (Pr2O3) budada beryahan dambe laga helay qiyaasaha badankooda. Nadiifinta sare ee aadka u sarreeya iyo isku-dhafka nadiifinta sare waxay hagaajiyaan tayada indhaha iyo waxtarka labadaba heerarka sayniska. Budada asaasiga ah ee Nanoscale iyo ganaaxyada, sida foomamka bedka sare ee beddelka ah, ayaa laga yaabaa in la tixgeliyo.
