Flash sintering of ceramic films: The influence of surface to volume ratio

Conference Dates

March 10-15, 2019


To establish the effect of sample thickness on the flash onset, we measure the sintering behavior of thin and thick films of 3 mol% yttria, the following is noted. (i) The onset of flash moves to a higher value for the thinner specimens. (ii) The power transition falls within a narrow band when the power is normalized with respect to surface rather than volume. (iii) Sintering of thinner specimens require a higher current density limit. These results point to a deeper significance of black body radiation than its use in estimating the specimen temperature in a steady state of flash.
