The properties of KDP type ferroelectrics with impurities (D in KH 2 PO 4 and H in KD 2 PO 4 ) are considered using the method of zero‐temperature Green function. The linewidth of the polarization waves caused by their scattering on such impurities as well as the local frequency of impurity itself are calculated. The obtained results can be tested by measuring an intensity of the coherent (for H in KD 2 PO 4 ) or incoherent (for D in KH 2 PO 4 ) inelastic scattering respectively of slow neutrons scattered by such impure ferroelectrics.
