Abstract:

In the work, we had studied the crystal BTNN10/90 experimental and simulated its piezoelectric properties. The aim of this work is to make a full characterization of the structural, dielectric and piezoelectric properties of the perovskite-structured oxides Ba_0,10 Na0,90 Nb0,90 Ti0,10 O3 (BTNN10/90), prepared by a conventional solid-state reaction method

Key words:

crystal, Piezoelectrics, X ray diffraction, BTNN, Perovskite.

Résumé:
