Abstract

In a process for producing polychrome ceramic shaped parts, at least two granulates formed from ceramic powder, binder and color-producing particles are shaped, subjected to binder removal and sintered. The granulates are formed from different color-producing particles and/or different concentrations of the same color-producing particles.
