  • Abstract
    The processing of porous PZT thick film ceramics on Al2O3 has been studied. The films were screen-printed from a thixotropic ink of PZT with a 58% solids content. The thick films were sintered between 1000°C and 1100°C for two hours. The sintered films show a 10 μm thickness and a average pore diameter ranging from 1 to 1.6 μm. The PZT forms a continuous skeleton that can be filled with the desired polymer. Dense and continuous PZT films were fabricated by screen-printing PZT ink on previously electroded Al2O3 substrates with Ag/Pd 70/30 paste. Densification of the PZT was obtaining by sintering near the liquidus temperature of the Ag-Pd system
