| Outline of Final Research Achievements |
Ordinarily, powder metallurgy is the basic process for producing ceramic parts.
However, the material’s volume changes during sintering.To eliminate the volume change of ceramics during sintering, in this study, we attempt to produce sintered alumina only by compressing alumina powder at room temperature.Then, alumina powder was subjected to high-pressure molding under vertical compression using the fabricated micro mold without lubrication at room temperature.Cross-sectional texture of the compressed body was observed using a scanning transmission electron microscope (STEM).The compressed ceramic powders did plastic deformation and judged it to sinter because there was less a cavity.
