Field-assisted sintering techniques (FAST) offer a way to lower firing temperatures and cycle times of sintering processes. The feature article in the January 2019 issue of Journal of the American Ceramic Society summarizes discussions from a workshop aimed at understanding the mechanisms behind FAST.
