Used in ceramic capacitors and electronic devices due to its dielectric properties. Acts as a stable, high-performance material in multilayer ceramic capacitors (MLCCs) for consumer electronics and automotive applications. Also employed in oxygen sensors and solid oxide fuel cells because of its ionic conductivity at elevated temperatures. Shows promise in photocatalytic applications for water splitting and environmental purification under visible light. Utilized in specialty glasses and coatings for thermal stability and resistance to crystallization.
