Fabrication of bimorph lead zirconate titanate thick films on metal substrates via the cold sintering-assisted process
A novel process was developed for the fabrication of 5–50 µm lead zirconate titanate (PZT)
thick films on metal substrates. Tape cast PZT with a methyl cellulose binder was burned out
at 275° C, humidified, and then partially densified at 300° C by cold sintering with a wet lead
nitrate liquid phase. Lamination of the green tape on dense metal foils led to incomplete
densification due to constrained sintering. However, when metal foils were replaced with
tape cast Cu, fully sintered PZT/Cu/PZT composites were acquired after a secondary heat …
