PIEZOCERAMIC MATERIAL Russian patent published in 2012 - IPC C04B35/472 H01L41/187

Abstract RU 2453518 C2

FIELD: construction.

SUBSTANCE: piezoceramic material on the basis of a system of solid solutions (1-x)BiScO₃-xPbTiO₃ contains oxides of bismuth, scandium, lead, titanium and chrome at the following ratio of components, wt %: Bi₂O₃ 26.0-29.0; Sc₂O₃ 7.6-8.5; PbO 46.0-49.0; TiO₂ 16.5-17.5; Cr₂O₃ 0.05-0.30.

EFFECT: material is characterised by lower value of dielectric losses and quite low value of mechanical quality at high temperature of Curie point, high values of dielectric permeability and piezoelectric characteristics.
