## Title

- title: Effect of Electric Field/Current on Sintering Behavior of Yttria during SPS
    Processing
  title_type: original

## Description

- description: The effect of electric field/current has been reported to enhance sintering
    behavior of various materials such as metals, ceramics and those composites. Although
    spark-plasma-sintering (SPS) technique has widely been utilized in the densification
    of various materials, the field/current effects on the sintering remain unclear.
    Especially for insulator materials such as oxides, the field/current effects in
    the SPS processing are under discussion. In this work, therefore, the field/current
    effects in the SPS technique were examined in yttria (Y2O3) ceramics by comparing
    the sintering behavior using conductive and non-conductive die set-ups. The sintering
    behavior of Y2O3 was apparently accelerated under the conductive set-up than under
    non-conductive die set-up. This suggests that during the SPS processing, applied
    pulsed electric field/current is likely to contribute to the sintering of Y2O3
    ceramics.
