| Abstract Scope |
This study reveals the optimization of bimodal powder by which bimodal powder affects the BJ process. Spherical alumina powder was used as a representative material. Three types of spherical alumina particles with different sizes were selected as fine (secondary) particles and mixed in varying proportions with coarse spherical alumina powder. Green bodies were fabricated from these powder mixtures, incorporating different sizes and amounts of the fine particles. The bulk densities, microstructures, and pore size distributions of the green bodies were characterized. The incorporation of fine particles significantly affected the green body density. |
