Flash sintering as a new sintering method for sintering of ceramic materials has been studied and effect of various parameter such as flash current density, time of flash and contact paste on properties of flash sintered 8YSZ samples has been investigated. Results showed it is possible to achieve high density in shorter time and lower temperature than conventional sintering methods. Samples could be sintered more than 95% theoretical density by electrical field 100V/cm, current density 160mA/mm2, and flash time of 30 sec at 800° С. The same density could be achieved by electric furnace and conventional sintering methods at 1400 °С for 4 hours. Results showed current density and temperature has positive effect on density. Also samples with LSM paste in lower current density had higher density relative to Pt paste ones.
