A second harmonic signal has been clearly observed in powders and ceramics of BaTiO3 in the high-temperature phase. The effect manifests itself at temperatures 500 K above the temperature of the phase transition from the tetragonal phase to the cubic

It is widely known that the ferroelectric phase transition from tetragonal to cubic phase in BaTiO3 ceramics and powders is strongly suppressed compared with the crystals. In our study the features of this transition were investigated by low-frequenc
