Abstract
A novel method for controlling the bulk structure of a ceramic green body has been proposed. In this method, spherical granules with uniform and several ten micronmeter size were placed mechanically in a regular array on a mesh with several centimeter square and then pressed to make a compact.(Granule assemblage). Defects and non-homogeneity in the granule compact govern a reliability of ceramics. In this method, a detrimental defects and non-homogeneity diminish. To demonstrate the potential of this method, alumina granules with several ten micron meter size were used as a model and a hexagonal close packed structure was made. Uniaxial pressing of this array can create a uniform and orderly structured green body.
