Abstract: | - In order to follow the minimization of integrated circuits, the capacitor industry has developd multilayer ceramic capacitors. BaTiO3 and others titanates were the first materials used for this purpose; however due to their high sintering temperature (>1300°C) it was necessary to use internal electrodes of costly noble metals (Pt and Pd). As an alternative, new ceramic composition such as PMN Pb(Mg 1/3 Nb 2/3)O3 having a high dielectric response and low sintering temperature (< 1000°C) has been extensively studied. The preparation is however difficult because of the formation of a stable parasitic phase which degrades its dielectric properties. Pure PMN powder and ceramic have been sintered using a new process of preparation: their physical characteristics are similar to those obtained with other sophisticated methods of preparation and of longer duration. |
