Abstract

The possibility of obtaining samples of lead-free piezoceramic by vibromolding under pressing pressure < 0.3 MPa is studied. The experiments were performed on the material K_0.49Na_0.49Sr_0.02NbO₃ synthesized by the standard ceramic technology of solid-phase synthesis. The samples of the piezoceramic fabricated by vibromolding are similar in terms of their properties to those obtained by static pressing under pressure 100 – 150 MPa. The advantages of the vibrocompaction process are: lower expenditures on tooling and equipment, smaller elastic deformation, and higher product density.
