摘要

This review summarizes the high-technology applications of yttria-partially-stabilized zirconia (YSZ) across multiple advanced engineering fields. Particular attention is given to its use in supercapacitors, where YSZ significantly improves device stability under prolonged cyclic operation, which is an essential requirement for practical deployment. In solid oxide fuel cells (SOFCs), YSZ exhibits exceptional performance as an electrolyte, anode component, and membrane material. It provides high oxygen-ion conductivity when operating in the 800 – 1000°C range, thereby directly influencing overall cell efficiency. In microelectronics, YSZ is utilized in thin-film transistors, where its exceptional dielectric properties and thermal stability facilitate the fabrication of reliable, high-performance electronic components. In aerospace and gas-turbine engineering, YSZ serves as a thermal barrier coating (TBC) for hot-section components, offering excellent resistance to extreme thermal loads. Various deposition techniques, including plasma spraying and chemical vapor deposition, are discussed, along with a detailed analysis of coating characteristics such as lamellar structure, porosity, crystallinity, and thermal stability.
