Abstract

Sintering behavior of 15% yttrium-doped barium zirconate (BaZr _{0 85}Y_{0 15}O_3-δ) and 15% scandium-doped barium zirconate (BaZr_{0 85}Sc_{0 15}O_3-δ) are investigated from the viewpoint of phase relationship. A relative density of more than 99% was achieved for BaZr_{0 85}Sc_{0 15}0 _3-δ, which is greater than that for BaZr_{0 85}Y _{0 15}O_3-δ. Larger grains were obtained for BaZr _{0 85}Sc_{0 15}O_3-δ whereas sintered BaZr _{0 85}Y_{0 15}O_3-δ was a mixture of larger and smaller grains. Scandium is a more promising dopant for barium zirconate from the standpoint of low density of the grain boundaries and uniform grains.
