Flash sintering is characterized by application of an electric field during furnace heating. It results in very rapid densification of ceramics, in most cases decreasing over an hour of sintering time to seconds. In this work, we investigate Laser Flash Sintering, which occurs under very rapid heating and cooling rates using a scanning carbon dioxide infrared laser as the heat source while simultaneously applying an electric field. Electric current is monitored during the highly dynamic realm of laser-induced flash sintering of 8% yttria-stabilized zirconia ceramic. Effects of electric field and lasing conditions on the early non-densifying region of flash sintering (Stage I) are presented.
