Outline of Final Research Achievements

The degree of enhancement of interdiffusion in the ceria-zirconia system increased as the Ce ion concentration increased, and showed a larger value under millimeter wave irradiation at any concentration. It is considered that this is because ceria absorbs millimeter waves more than zirconia, and thus the the driving force of diffusion depends on Ce ion concentration. Both the electric furnace and millimeter wave diffusion improved the Vickers hardness of the titania through the mutual diffusion contacted with tin oxide, but the flexural strength improved only by the millimeter wave diffusion annealing. It was possible to perform low temperature sintering by millimeter wave heating to ceria and zirconia with small substitution amount, which suggested cation migration promotion. It was also possible to suppress grain growth and bending deformation, suggesting related cation migration suppression

Academic Significance and Societal Importance of the Research Achievements

ミリ波照射により拡散が促進され、その度合いがミリ波吸収に依存することがわかった。またこれまでは促進一辺倒であったミリ波照射効果であるがある条件では抑制もありうることが示された。
