· SrHfO3

Strontium hafnate (SrHfO3) is a ceramic compound belonging to the perovskite oxide family, combining strontium and hafnium in a stable crystalline structure. This material is primarily investigated in research and emerging applications for high-temperature stability, dielectric properties, and chemical inertness, making it a candidate for advanced thermal barriers, electronic substrates, and environments where conventional ceramics face degradation limits.
