Abstract

“Flash sintering” occurs when an electrical potential difference is applied across a ceramic powder compact and is characterised by an electrical power surge at a specific combination of electric field and temperature, accompanied by extremely rapid densification. The phenomenon is easy to reproduce but the mechanisms responsible remain controversial. This paper reviews the evidence available and examines the thermo-electrical response and densification at high heating rates, concentrating mainly on 3YSZ, which was the first ceramic to be sintered in this way and on which most research has been conducted. The mechanisms which may be responsible for the phenomenon are discussed and areas requiring further investigation are highlighted.
