Abstract

The potential of high frequency (30 GHz) microwave sintering has been investigated in field of sintering Y₂O₃ stabilized, tetragonal and cubic ZrO₂ in comparison to conventional sintering techniques. Therefore by electrophoretic deposition improved green bodies were produced with high green densities and homogeneous pore size distribution. After systematic variation of sintering parameters, the subsequent characterization of the sintered samples has been focused on the influence of microwave sintering to the microstructure evolution.
