The possibility of obtaining ceramic elements of a piezoelectric applicator by vibration molding is considered. This article dwells on conventional materials of lead zirconate titanate family and prospective lead-free ferroelectric materials of potassium-sodium niobate and barium titanate families. The compactibility degree was studied for a powder with an average particle size of 1–2 μm depending on the vibration frequency in the range of 50– 1100 Hz and the vibration amplitude ranging from 10 to 200 μm. The optimal conditions for the vibration molding of samples were determined. Piezoceramic samples made by vibration molding at pressures up to 1.3 MPa are similar in their characteristics to ceramic samples obtained by static pressure molding at pressures of 100-150 MPa.
