High-temperature piezoelectric polycrystalline ceramics of the system (1−x)(Bi 1−y La y )FeO 3 -xPbTiO 3 (BF–PT), which are mixed phase in their consolidated state, have been investigated by in situ neutron diffraction during the application of uniaxial compressive stress. It is suggested that the achievable strain in BF–PT is largely generated by straining of...
Poling of piezoelectric ceramics is required to induce piezoelectric behaviour. A new method has been designed to apply a transverse mechanical stress while applying an axial electrical field. The effect of this combined loading method on polarization and piezoelectric coefficient is studied as a function of loading path, electric field and mechanical stress. Due to this treatment, the electrical...
