Praseodymium orthoscandate is a chemical compound, a rare-earth oxide with a perovskite structure. It has the chemical formula of PrScO3.

Preparation

[edit]

Praseodymium orthoscandate can be obtained by reacting praseodymium(III,IV) oxide with scandium oxide.[1]

Properties

[edit]

Praseodymium orthoscandate is a green solid. It has an orthorhombic perovskite-type crystal structure with space group Pnma (space group No. 62).[1]

In 2021, with the help of electron ptychography, researchers were able to achieve the highest magnification. In this way, the researchers managed to enlarge the atoms of a praseodymium orthoscandate crystal by a factor of 100 million.[3][4]
