摘要：

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 and 1150 degrees C for 2 h. The sintered films show a 10 mu m thickness and an average pore diameter ranging from 1-2 mu m. 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 obtained by sintering near the liquidus temperature of the Ag-Pd system.
