Abstract :
Na0.5Bi0.5TiO3 doped with varying levels of BaTiO3 (BT) was synthesized. Remnant polarization, coercive field, d33, permittivity and grain size were measured. Output voltage generated under fast impact was measured. The piezoelectric doped with 4 mol.% BT generated the highest output voltage and was selected for explosive impact testing. Results showed that it generated an output voltage twice that of the standard of PZT-5A..
