Sr₂HfO₃ is a strontium hafnate ceramic compound belonging to the perovskite family of oxides, characterized by a double-perovskite crystal structure. This material is primarily investigated in research contexts for high-temperature structural applications and as a thermal barrier coating candidate, where its hafnate base provides excellent oxidation resistance and refractory properties. Engineers consider Sr₂HfO₃ for extreme-environment applications requiring chemical stability and thermal durability beyond conventional oxide ceramics, particularly in aerospace and power generation sectors exploring next-generation materials.
