Abstract
In this paper we discuss electron microprobe results from WRh AMTEC electrodes tested in sodium exposure test cells. We compare and contrast the morphology and elemental distribution of WRh electrodes in the as sputtered condition with those after up to 1250 hours in sodium vapor at temperatures of 800-900°C
