HfO2

Notas

Hafnium(IV) oxide, represented by the chemical formula HfO2 and often referred to as hafnia, is a highly stable, colorless inorganic compound. Within the context of materials science, it functions as an electrical insulator characterized by a substantial band gap ranging from 5.3 to 5.7 eV. As a stable oxide of hafnium, it serves as a critical intermediate in the refinement processes used to produce hafnium metal.
