Abstract
Densification behavior and crystallite growth were investigated for alumina-YSZ composites by examining sintering behavior under 28 GHz millimeter-wave radiation. Enhancement of sintering in the intermediate stage by millimeter-wave radiation was suggested from the analysis on densification behaviors for alumina-YSZ composites as well as alumina. These ceramic composites under millimeter-wave radiation have been proved to densify with suppressing crystallite growth of alumina, compared with those by conventional sintering method.
