Morphological and Surface Chemical Characterization of Fine ZrO2 Particles for Ceramic Applications
In the last decade a great deal of work has been devoted to the characterization of Yttriastabilized tetragonal ZrO2 (YSTZ), because of its large use as a ceramic material. Many efforts have been made to evaluate some macro- and mesoscopic characteristics of YSTZ, such as those obtained by mechanical tests (e. g., shrinkage, sinterability, KIC, specific surface area SSA, etc), whereas only little attention has been focused so far on the evolution of the nanostructural and surface reactivity features of the starting powders. It is normally observed that YSTZ precursors, that have been preliminarly treated in different conditions, exhibit quite different sintering behaviours.
