摘要

The demand for low power consumption electronic components calls for the development of low-loss dielectrics for Multilayer Ceramic Capacitor (MLCC) cofired with Cu electrodes. In the present study, 0.7PbMg1/3Nb2/3O3-0.3PbMg1/2W1/2O3 ceramic has been found to have a potential application on Cu-cofired MLCC without any dopant. A single perovskite phase was synthesized from the columbite method using MgNb2O6 and MgWO4 as precursors. Phase composition, surface morphology, and valence state of ceramic samples sintered in different atmospheres are analyzed using XRD, SEM, and XPS. When the ceramic is cofired with Cu in an N2 atmosphere, the dielectric measurement shows high dielectric constant (~ 2000) and low dielectric loss (< 0.001 at 10 kHz–1 MHz). No dielectric peak and relaxor characteristics were found in the temperature range from −55 to 125 °C, indicating paraelectricity for the ceramic.
