Abstract. Yttria-stabilized zirconia (YSZ) has been studied as a promising material for application as an electrolyte in solid oxide fuel cells. In this work YSZ powders ( ( x Y 2 O 3 − (1 − x )ZrO 2 ) x = 5 8 and 10 mol ) were synthesized by three different methods co-precipitation sol–gel combustion and sol–gel.
