Ca1 Hf1 O3
semiconductor· Ca1 Hf1 O3
Calcium hafnium oxide (CaHfO₃) is a ternary ceramic compound belonging to the perovskite oxide family, primarily investigated as an advanced functional material in materials science research. While not yet widely commercialized, this compound is of interest for high-temperature applications and electronic devices due to hafnium's exceptional refractory properties and the perovskite structure's versatility for tuning electrical and thermal characteristics. Engineers consider hafnium-based oxides when extreme thermal stability, chemical inertness, or specialized dielectric/photonic properties are required in demanding environments.
