Pulverization process of agglomerated Pd powder synthesized by wet chemical method was investigated. Pd slurry was prepared by mixing zirconia media and agglomerated Pd powder with normal hexane. And pulverization was conducted by pouring the Pd slurry on to slant board. Agglomerated Pd particles are loaded with shear force during flow on slant board and to be pulverized. The pulverization was evaluated by measurements of green density, surface roughness, shrinkage, and electrical resistivity of screen printed Pd electrode. And also pulverized Pd powder was subjected to SEM observation. The result indicated that the pulverization was strongly influenced by slurry flow length and a gradient of slant board which related to slurry flow rate.
