Abstract

β″-Alumina, the electrolyte of choice of sodium/sulfur and sodium/metal chloride batteries and alkali-metal thermal-electric converters, was sintered from precursor phases to high β″-phase purity in less than 15 s from the onset of densification by rapid pass-through rf induction coupled plasma sintering. The maximum instantaneous shrinkage rate was 1.8%/s. The resistivity was measured to be 13.8±1.4 Ω·cm. The rapid conversion found is a significant improvement over conventional processing of β″-alumina, which requires extended postsintering annealing times to obtain high β″-phase purity.
