Yttria fully stabilized zirconia (with 8 mol% Y₂O₃) is a commonly used and well characterized ceramic electrolyte material.  YSZ-8 is used as an SOFC electrolyte membrane in solid oxide fuel cells and as a component in composite cathodes or cermet anodes.  The surface area and particle size characteristics of this YSZ-8 powder make it well suited for tape casting processes, but it also can be used for pellet pressing, extrusion and other ceramic manufacturing processes.
