Undoped Y 2 O 3 polycrystals were densified by flash sintering under DC or AC electric field
with varying holding times up to 60 min, and their chemical bonding state and crystal …

Abstract 1 mol% Ni 2+-doped Y 2 O 3 shows flash-sintering at DC fields greater than 300
V/cm. When compared to the undoped Y 2 O 3, the onset temperature for the flash event is …

Frequency dependence of the densification behavior of undoped Y 2 O 3 sintered by the AC-
flash sintering was systematically investigated at 500 V· cm− 1 over a frequency range from …

The amount of excess oxygen vacancies that are generated during FAST regime of direct-
current flash sintering was estimated semi-quantitatively for 3 mol%–10 mol% Y 2 O 3 …

It is widely acknowledged that electrochemical reduction occurs during DC flash sintering
(FS) of YSZ. In situ experiments have shown the emergence of new phases during FS that …

Doping effect of 1 mol% divalent, trivalent or tetravalent cations on the flash sintering of Y 2
O 3 was investigated under DC electric fields ranged from 0 to 1000 V cm− 1. The examined …

A mixture of pure monolithic ZrO 2 and Y 2 O 3 powders was flash-sintered at different
holding times. The results show that flash-sintering led to a rapid phase transformation: The …

Fig. 1. Plots showing linear shrinkage (red curves) and power dissipation (blue curves)
behaviors during flash sintering and SCF sintering. The horizontal axis is plotted from the …

The onset of flash sintering is generally considered to be predominantly a function of the
conductivity of a given ceramic, the furnace temperature, and the electric field. However, the …

The recently discovered flash sintering technique has shown that the application of a
sufficiently large dc electric field (E-field) to a ceramic during sintering can cause sintering at …
