HfZrO3 is a mixed-metal oxide ceramic composed of hafnium and zirconium, belonging to the class of high-entropy or dual-cation refractory oxides. This material is of primary interest in advanced semiconductor and high-temperature applications where its thermal stability, chemical inertness, and structural properties offer advantages over single-component alternatives. The hafnium–zirconium combination is explored in gate dielectrics for next-generation microelectronics, thermal barrier coatings for aerospace engines, and solid-state electrolytes for energy storage, where the mixed-cation structure can suppress phase transitions and enhance performance over a wider operating range.
