Pyramidal Structures on Yttria-Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material
1 Introduction Thermal barrier coating (TBC) systems have been used for many decades to continuously improve and enhance the performance of hot section components, e.g., in modern gas turbines [1]. TBC systems reduce the temperature at the surface of the metallic turbine material, allowing either higher operating temperatures for the whole system or leading to longer lifetimes [2].
Constrained flash sintering of gadolinium‐doped ceria thin layers
1 INTRODUCTION Solid oxide cells (SOCs) are electrochemical devices and are among the multiple green solutions to address the growing global energy demand. Their fundamental structure consists of two porous electrodes separated by a dense electrolyte layer. The electrochemical reactions take place in the electrodes at the triple phase boundaries, where the respective reaction gases, ionic conducting, and electronic conducting phases are in contact.
Erbium aluminum perovskite ceramics with superior plasma etching resistance
1 INTRODUCTION Ever since its declaration in 1965, semiconductor industry kept Moore's law alive by putting more and more effort into further refinement of the semiconductor manufacturing process. This complex process can be broken down into three different steps: patterning, etching, and doping.
Towards a scalable recycling process for ceramics in fuel-electrode-supported solid oxide cells
Towards a scalable recycling process for ceramics in fuel-electrode-supported solid oxide cells† The solid oxide cell (SOC) technology relies on high-performance ceramics containing strategically valuable and critical raw materials. This study focuses on the processing of spent cell materials from fuel-electrode-supported SOCs, demonstrating the feasibility of utilizing a significant portion of the ceramic cell in a closed-loop system.
