Estimation of Homogeneity in Pulsed High Current Sintering by Crystallographic Character of Consolidated Anatase

Abstract

Radial homogeneity in the pulsed high current sintering was estimated by consolidation behavior of anatase nano-powder with 9nm and the change of its crystallite size and preferential orientation. Radial distributions of density, crystallite size and the degree of preferential orientation showed a concave curve with a minimum at the central position against radial distance. It is suggested that the concave distributions arise from the corresponding distribution of current density.
