Application of BaTIO3 perovskite material for piezoelectric multilayer actuators

Abstract

In this paper, the results of the manufacturing of BaTiO3 material destined for use in stacked-disk multilayer actuator production are presented. SEM microstructures and electric properties of the fabricated pellets are presented and discussed. The dilatometric curve was executed using the high temperature dilatometer in order to determine at which temperature barium titanate pellets and beams should be sintered to receive full dense sinters. Finally, the problem of metal layer deposition on barium titanate ceramics during actuator fabrication is considered.
