Abstract
Effects of alumina addition on ionic conductivity for alumina/8YSZ composit e was examined in which conductivity shows a slight increase with alumina a ddition. The alumina addition has a role in increasing the 8YSZ/8YSZ interf ace (grain boundary) by suppressing the matrix grain growth as well as incr easing the population of the alumina/8YSZ interface. The increase in ionic conductivity in composite was suggested not to be ascribed to the alumina/8 YSZ interface but to the grain boundary. (C) 1999 Elsevier Science B.V. All rights reserved.
