Brazing perovskite ceramics with silver/copper oxide braze alloys
Source abstract
Abstract
In this study the feasibility of eutectic braze alloys based on the silver/copper oxide (Ag/CuO) system were investigated for use in joining lead magnesium niobate (PMN) ceramics. PMN was successfully brazed in air at 1050 and 1100°C using Ag/CuO alloys. The brazed samples had an average four-point-bend fracture strength of approximately 40 percent of the average monolithic PMN strength (with an actual value of 19 ± 11 MPa). The fracture strength was relatively constant for all brazing conditions tested. No significant reaction product layer was observed at the silver/PMN interface and the electrical properties of the PMN were changed only slightly by presence of the braze alloy interlayers.
