Chemical compound

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

Preparation

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

Properties

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

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.
