Role of Oxide Additives in Stabilizing Zirconia for Coating Applications

Abstract : Zirconium dioxide (ZrO(2)) is a ceramic with a variety of industrial applications as a refractory material, and it is used in electronic packaging, biomedicine, and advanced engines. Unfortunately, pure zirconia undergoes a destructive phase transformation that severely limits its uses. However, some oxide additives have been found to control this transformation and ultimately lead to significant improvements in the material. This report summarizes the role that oxide additives play in controlling these transformations, and the resulting applications of ZrO(2)-based coatings are discussed.
