Abstract

Warpage evolution during co-firing of multilayer ceramics was systematically recorded and analyzed. LaSrMnO3 was screen printed on one side of a green sheet of yttria stabilized zirconia and/or NiO-YSZ was screen printed on the other side. During co-firing warpage due to the mismatch in sintering shrinkage was observed. The radius of curvature continuously changed as temperature increased. The curl was strongly influenced not only by the mismatch in sintering strain but also by the changing viscosity of the components. The mechanical stress in the bilayer was calculated from the sintering strain and viscosity data obtained from thermomechanical analysis using cyclic loading dilatometry. A strategy for reducing warpage in such systems is presented.
