• Functionally graded porous Nb-doped PZT material (PZTN) was produced by addition of pore forming agents and tape casting. Stacked layers with different content of carbon black (CB) were co-fired and a porosity gradient was obtained. Tailoring the binder to plasticizer volume ratio of each single green layer, gradually increasing CB content and adjusting the binder burnout procedure are the critical issues to eliminate cracks and delaminations and develop crack-free porosity-graded multilayer with porosity ranging from 10 to 30 vol%. A load applied during the heating treatments was required to obtain a warpage-free, 400 µm thick, planar multilayer specimen. Layers with different pore former content show different shrinkage values that can cause delamination or warpage during sintering. These differences are reflected in strain rate mismatch and can be influenced by the layer thickness and viscosity ratio. The piezoelectric properties of these materials are suitable for ultrasonic applications (literal)
