PIEZOELECTRIC CERAMIC MATERIAL Russian patent published in 2015 - IPC C04B35/495

Abstract RU 2548278 C1

FIELD: chemistry.

SUBSTANCE: piezoelectric ceramic material contains oxides of sodium, niobium, strontium, lithium, aluminium, bismuth and iron with the following component ratio, wt %: Na₂O 16.32-16.40, Nb₂O₅ 79.81-80.20, SrO 0.63, Li₂O 1.12-1.13, Al₂O₃ 0.40, Bi₂O₃ 0.92-1.28, Fe₂O₃ 0.32-0.44.

EFFECT: reduced value of the relative dielectric permeability and increased value of electromechanical connection coefficient of the planar mode of vibrations with the preservation of sufficiently high values of mechanical quality.
