Alumina 99.8% pure was Flash Sintered under different fields and currents in the range of 500-1500 V/cm and 2- 6mA/mm2, respectively. It was shown that the considered material can be sintered down to 900°C and that the current density is controlling the shrinkage upon sintering. The analysis of the microstructure evolution pointed out that the porosity-grain boundary separation is enhanced by increasing the current.

Abstract
Alumina 99.8% pure was Flash Sintered under different fields and currents in the range of 500-1500 V/cm and 2- 6mA/mm2, respectively. It was shown that the considered material can be sintered down to 900°C and that the current density is controlling the shrinkage upon sintering. The analysis of the microstructure evolution pointed out that the porosity-grain boundary separation is enhanced by increasing the current.| File | Dimensione | Formato | |
