Dense (K0.451Na0.503Li0.06) NbO3(KNLN) ceramics can be obtained with CuO-addition by conventional processing routes at low sintering temperature of 890℃.Liquid phase was found in CuO-doped KNLN ceramics as shown by scanning electron microscopy,which promotes densification and ensures homogeneous growth of grains.
