TLDR
In this paper, optical and thermal properties of anion vacancies are reviewed in some detail and shown unlikely to accommodate the formation of aluminum colloids below ≈ 750 K. These colloids had been previously proposed to account for an anomalous conductivity which has been reported in alumina after prolonged irradiation at elevated temperature under an applied electric field.About:

Field assisted and flash sintering of alumina and its relationship to conductivity and MgO-doping
TL;DR: In this article, the authors show that flash-sintering in MgO-doped alumina is accompanied by a sharp increase in electrical conductivity, which is not a cause-and-effect relationship, but instead that the concomitant increase in the sintering rate and the conductivity share a common mechanism.
