Effects of Densification Mismatch on Stress Development During Cofiring Ag-Based Multilayer Ceramic Laminates

Stress and camber development during cofiring a bi-layer Ag/ BaTi4O9+ZnO-B2O3 glass (BTZB) laminate are caused by the densification rate mismatch between Ag and BTZB layers. A small amount of TiO2, 1.22-3.67 vol%, is added into Ag paste to reduce the densification rate mismatch between Ag and BTZB layers, which results in a smaller sintering mismatch stress generated and defect-free multilayer Ag/BTZB laminates. The camber development during cofiring the bi-layer Ag/BTZB laminate measured experimentally is in good agreement with that calculated by using the linear shrinkage rate difference between Ag+3.67 vol% TiO2 and BTZB laminates.
