WebScandate cathodes have long attracted attention due to their higher emission current density, apparent low work function, and anticipated improved longevity compared to conventional cathodes. However, scandate cathodes have not been applied as extensively as their potential would imply. WebUnlike simple materials such as a binary alloy or binary oxide system, impregnated scandate cathodes contain various multi-element compounds, scandia-doped W powder mixes, and impregnate materials. In addition, numerous complex reactions occur during the fabrication steps, principally during impregnation and activation processes [27,34]. WebMar 21, 2024 · Abstract In this paper, gadolinium scandate (GdScO 3) has been synthesized at 300 °C through the decomposition of a mixed cation hydroxide hydrogel in a humid environment. Increasing the reaction temperature produced larger particles that better adopted the Wulff shape. brazil japan 2006
