Praseodymium orthoscandate is a chemical compound, a rare-earth oxide with a perovskite structure.

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

[1] Praseodymium orthoscandate is a green solid.

[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 so as to present each atom as a separate entity, easily identifiable by element.
