It is well known that the undoped Pb(Mg1/3Nb2/3)O3-PbTiO3 ceramics, prepared through conventional ceramic processing, present no evident aging effect. In this paper, however, a discernible aging phenomenon was observed in an undoped, N2-H2-annealed ceramic. When this sample was later annealed again in air, this effect became negligible again just like that of a normally prepared PMN—PT ceramic. The valence states of Ti ions, which may be changeable in different annealing atmospheres, were assumed to be responsible for the different degrees of aging.
