“…Over the last two decades hafnia (HfO 2 ) and zirconia (ZrO 2 ) have gained considerable attention because of their important applications in various fields. Besides being used as ceramic and refractory materials, they have also been employed as components in superhard materials, gas sensors and solid oxide fuel cell electrolytes . Because of the high refractive index and high laser damage threshold of HfO 2 films, hafnia can be used in high power laser mirrors .…”

Hafnia (HfO 2 ) and zirconia (ZrO 2 ) are of great interest in the quest for replacing silicon oxide in semiconductor field effect transistors because of their high permittivity. Both exhibit extensive polymorphism and understanding the energetics of their transitions is of major fundamental and practical importance. In this study, we present a systematic thermodynamic summary of the influence of particle size on thermodynamic phase stability in hafnia and zirconia using recently measured enthalpy data from the literature. The amorphous phase is found to be the most

“…It has been widely used or proposed for a wide range of applications, such as in oxygen sensors, an electrolyte in solid oxide fuel cells, ceramic cutters, orthopedic implants and nuclear waste immobilization [1][2][3][4]. Cubic ZrO 2 is isostructural with urania, plutonia, and thoria nuclear fuel compounds, and it is also one of the most radiation resistant ceramics, which makes ZrO 2 a model system for studying the irradiation response of ceramic oxides in extreme radiation environments [5][6][7][8][9].…”

“…In this particular case, the lambda-probes work at temperatures higher than 600 • C for functional and environmental reasons [1][2][3]. However, for other applications in the medical field, food processing and waste management industries, oxygen monitoring at lower temperatures, for example, in the range from room temperature (RT) to 350 • C, is more important.…”
