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 characteristics of this spray-dried YSZ-8 powder make it well suited for pellet pressing and other ceramic manufacturing processes where a highly flowable powder is desired.  The high surface area of this powder enables lower sintering temperatures.
