abstract = {Flash sintering is a novel electric field and current
assisted sintering technique which densify ceramics at
moderate furnace temperature and in short time (few seconds)
as compared to the conventional sintering techniques. The
onset of flash encompasses three unique characteristics, (i)
non-linear rise in conductivity, (ii) luminescence and (iii)
rapid densification. the mechanism behind the flash
phenomena is not fully understood yet. The present work
experimentally demonstrated that the densification in flash
sintering is primarily dominated by Joule heating. Herein,
we distinguished the onset of flash and the degree of
densification of cubic zirconia in sintering atmospheres
with different oxygen partial pressures. In this study, we
demonstrate that the flash onset temperature and
densification are independently influenced by the sintering
atmosphere during flash sintering. Furthermore, the extent
of densification is not directly influenced by the current
density rather, by the power dissipated in the sample.},
