Rapid thermal processing of Pb(Mg sub 0. 7 Zn sub 0. 3 ) sub 1/3 Nb sub 2/3 O sub 3 multilayer ceramic capacitors
- New York State College of Ceramics, Alfred Univ., Alfred, NY (US)
Fast firing, with total sintering times of between 3 and 15 min, was utilized to process multilayer ceramic capacitors of dielectric composition Pb(Mg{sub 0.7}Zn{sub 0.3}){sub 1/3}O{sub 3}. This dielectric composition has been studied extensively because of its diffuse phase transition, which is intrinsic to relaxors and also its high dielectric constant. The fast-firing procedure, which did not utilize any prevention for PbO volatilization, has been shown to be a feasible method for the processing of these components. Sintering times in the range of 12 to 15 min at 1100{degrees}C resulted in components with weak field dielectric constants in excess of 12000 and grain size in the range of 1 {mu}m or less. The development of a pyrochlore phase at the component surfaces was less influential on the dielectric performance of the components because of the internal nature of the electrodes.
