• The dielectric response of K...(NH...)...H...PO...-SiO... composite prepared by embedding of corresponded salts into porous SiO... glass with 320 nm average pore diameter has been studied at the temperature range of 10-300 K. The transition from paraelectric to antiferroelectric (AFE) phase in implanted particles is detected at T ... 45 K. Below ... 20 K the specific dispersion of dielectric response indicates a transition into proton glass (PG) state. It was found that the average time of dielectric relaxation follows the empirical Vogel-Fulcher law. Obtained results speak in favor of the coexistence of AFE and PG phases at low temperatures.
