Description

Zirconium Oxide Yttrium Stabilized (Yttria-Stabilized Zirconia, YSZ) is a high-purity ceramic material renowned for its exceptional thermal stability, mechanical strength, and ionic conductivity. Composed of zirconium dioxide (ZrO2) stabilized with yttrium oxide (Y2O3), this advanced oxide ceramic exhibits remarkable resistance to thermal shock, wear, and corrosion, making it ideal for demanding industrial and research applications. The molecular formula O5Y2Zr reflects its precise stoichiometry, ensuring consistent performance in solid oxide fuel cells (SOFCs), oxygen sensors, and high-temperature structural components. Available in powders, pellets, or custom forms, our YSZ meets stringent purity standards (≥99.9%) with controlled particle size distributions for optimized sintering and performance. Its cubic crystal structure, stabilized by yttrium doping, enhances oxygen ion mobility, critical for electrochemical applications. Packaged under inert conditions to prevent moisture absorption, this material is a cornerstone in materials science, energy research, and advanced ceramics engineering.

Application

Yttria-stabilized zirconia (YSZ) is widely used as an electrolyte in solid oxide fuel cells (SOFCs) due to its high oxygen ion conductivity at elevated temperatures. It serves as a thermal barrier coating (TBC) in jet engines and gas turbines to protect metallic components from extreme heat. In analytical chemistry, YSZ is employed in oxygen sensors for automotive and industrial emissions monitoring. Its biocompatibility also makes it suitable for dental implants and prosthetic applications.
