Influence of AgNbO 3 doping on structure, microstructure, dielectric, ferroelectric and local piezoelectric properties of (K 0.5 Na 0.5 )NbO 3 ceramics was studied. Decreased in the unit cell parameters correlated with ionic radii changes. High effective local d 33 piezoelectric coefficient values (800 pm/V) were observed in compositions studied.
