MATERIAL FOR ELECTROSTRICTOR Russian patent published in 2019 - IPC C04B35/499 H01L41/187

Abstract RU 2696729 C1

FIELD: physics.

SUBSTANCE: invention relates to production of electromechanical products and ultrasonic emitters. Disclosed is material for electrostrict based on solid solutions, including PbO, MgO, Nb₂O₅ and TiO₂ and additionally containing Bi₂O₃ and Sc₂O₃ oxides,wherein said material has composition (1-2x) BiScO₃⋅xPbTiO₃⋅xPb (Nb_2/3Mg_1/3) O₃ at x = 0.42.

EFFECT: invention provides lower dielectric permeability while maintaining good electrostriction deformation.
