Abstract

Received December201995Accepted March151996 (CeO2)1x(GdO15)x is a possible candi(1ate as an elcctrolyte in a low temperature solid oxide fuel celL This paper describes how Raman spectroscopy can be use(i to detemne the structural changes observed with increasing G(1203dopant concentrationThe mechanical properties of(CeO2)o8(GdO15)o2were also detemhnedThe4-point bend strengthfor examplewas found to be143104MPa at room temperatureand11471Lg MPa at800CThe paperalso describes several methods for detemning the fracture toughness of(CeO2)o8(GdO15)o2at room temperature
