Electrophoretic deposition (EPD) is one of the colloidal processes during in ceramic production and has gained significant interest because of the high versatility of its use with different materials including nanoparticles and its cost-effectiveness requiring simple equipment. Of the major parameters for ceramic processing involving the EPD, preparation of the suspensions and application methods of electric fields are particularly important factors that affect the microstructure. At the beginning of this review, we introduce the fundamental aspects of the EPD processing. We then focus on the following four points: (1) the stability of the Pb(Zr,Ti)O2 /ethanol suspension by the addition of phosphate esters and its influence on the subsequent EPD process, (2) the stability of a TiO2/(2-propanal+2.4−pentanedione) suspension, which is a suspension without dispersants, (3) the film performance of the pulsed direct current EPD using an aqueous suspension, and (4) the laminated textured ceramics by EPD in a strong magnetic field.
