Abstract

Recently, flash sintering has been expanded to synthesize complex oxides in a few seconds at low furnace temperatures. It is called ‘Reactive Flash Sintering (RFS)’. Here, we study reactive flash sintering of MgO-Al₂O₃ to MgAl₂O₄. 8YSZ was added as a flash catalyst, since MgO and Al₂O₃ could not be flashed by itself within our experimental condition. We show that one-step flash experiment produces polycrystals of high density, also the transformation of magnesia and alumina into single-phase spinel.
