Insights into reactive flash sintering of MgO-Al2O3-(8YSZ) by in-situ synchrotron X-ray diffraction
March 10-15, 2019
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.
