Calcium niobate (Ca₂Nb₂O₇) is a complex oxide ceramic compound belonging to the pyrochlore family, valued for its thermal stability and ionic conductivity properties. This material is primarily investigated for solid-state electrolyte and thermal barrier coating applications in high-temperature energy systems, where its ability to conduct oxygen ions at elevated temperatures makes it an alternative to conventional yttria-stabilized zirconia in specialized fuel cell and thermochemical energy conversion contexts. Its development is driven by the need for improved performance in extreme thermal environments where conventional ceramics face limitations.
