AbstractThe alkali niobate ferroelectrics ((K0.5Na0.5)NbO3, KNN) are promising candidates as alternatives for PZT (Pb(ZrxTi(1-x))O3) ceramics in piezoelectric technologies. In order to obtain dense compounds with desirable properties, CuO has been used as sintering aid. In this work, the defect chemistry of Cu2+ doped KNN was investigated by means of electron paramagnetic resonance (EPR). Copper is found to be incorporated as acceptor-type centers on B-site in the perovskite structure and, due to charge compensation, two kinds of mutually compensating defect dipoles are formed.
