Widely used in high-performance ceramics due to its exceptional thermal stability and mechanical strength. Commonly applied in solid oxide fuel cells (SOFCs) as an electrolyte material because of its high oxygen ion conductivity at elevated temperatures. Utilized in sensors, particularly oxygen sensors in automotive and industrial applications, thanks to its ability to conduct ions while remaining airtight to gases. Frequently found in biomedical applications such as dental and orthopedic implants, where its biocompatibility and wear resistance are critical. Also employed in coating technologies for turbine blades and other high-temperature components to provide thermal barrier protection. Its nano-scale particle size enhances sinterability and improves density at lower temperatures, making it ideal for advanced manufacturing processes.
