TLDR
In this paper, a 10-μm PZT film was formed from the same starting powder and exhibited a polarization hysteresis equivalent to that of a bulk sample, with a remnant polarization of 33μC−cm−2.Abstract:
Electrophoretic deposition (EPD) is a simple, rapid, and low cost method for forming dense lead zirconate titanate (PZT) films down to 5 μm from particulate precursors. The three main steps of this process are: (1) formation of a charged suspension of the starting PZT powder; (2) deposition of the powder particles on an electrode under the influence of a dc electric field; and (3) fluxing and constrained sintering of the resulting particulate deposit at 900°C to form a dense continuous film. A 10 μm film formed using this process exhibited a polarization hysteresis equivalent to that of a bulk sample formed from the same starting powder, with a remnant polarization of 33 μC cm−2.read more

Fabrication of Dense Zirconia Electrolyte Films for Tubular Solid Oxide Fuel Cells by Electrophoretic Deposition
TL;DR: In this paper, a simple suspension chemistry (8-mol%-yttria-stabilized zirconia particles in acetic acid) yields films of similar quality to those from conventional approaches (such as electrochemical vapor deposition), but at potentially much less expense.

Electrophoretic Deposition (EPD): Mechanisms, Kinetics, and Application to Ceramics
TL;DR: In this article, a method of determining the Hamaker constant of suspended particles is developed by modeling the relationship between the particle inter-action energy and the suspension stability, and a three-probe dc technique is used to map the voltage profile around the depositing electrode and the results are used to explain discrepancies between the calculated and experimentally observed voltage drops during deposition.

Thin/thick piezoelectric films by electrophoretic deposition
TL;DR: In this article, the use of EPD for forming fully dense Lead Zirconate Titanate (PiT) films of twenty microns and less was discussed, and three main steps as applied to PZT are covered: 1. Formation of a charged SUSCi15IOfl of the startingsub-micron PiT powder. 2. Deposition of the powder particles on an electrode under the influence of a l)C electric field. and3. fluxing and constrained sintering of the resulting particulate deposit to form a dense continuous fil
