The dielectric properties of ferroelectric composite (NH4HSO4)x/(PbTiO3)1-x is studied for x ranging from 0,00 to 0,50. Measurements of permittivity were performed by heating-cooling mode temperature range from 130 K to 380 K. The value of the temperature interval of existence of the ferroelectric phase increases by ~5 degrees and independent at the volume fraction of particulate inclusions in composites. It is shown that the inclusion of PbTiO3 particles gives rise to hysteresis upper temperature phase transition, which may indicate a change in the type of phase transition of the second order on the first-order phase transition.
