Paper Title:
Phase Stability and Dielectric Properties of Low Temperature Fired BaTi4O9 Microwave Material with Copper Electrodes in Reducing Atmosphere
  Abstract

In this study we report sintering behavior and microstructures of glass-added BaTi4O9 microwave dielectric ceramics with copper paste in reducing atmosphere. Experimental results show a buffer layer may form at the interface of Cu-electrode and BaTi4O9 microwave dielectric ceramics if the glass did not diffuse smoothly during sintering, and therefore materials exhibited different colors. X-ray results indicate that Cu reacted with Ba seriously to form complicated reaction products, and some BaTi4O9 transformed to barium titanate with various ration of Ba/Ti, which may degrade the dielectric properties of materials.
