We describe the conditions of hydrothermal synthesis of solid solutions based on ferroelectric single-crystals of antimony orthoniobate (SbNbO/sub 4/), and some of their physical characteristics are studied. We considered the problem of introducing bismuth oxide (III) as the substituent ion into the SbNbO/sub 4/ structure directly in the process of hydrothermal crystallization of this compound. The crystallization was performed in the multicomponent system Sb/sub 2/O/sub 3/-Nb/sub 2/O/sub 5/-Bi/sub 2/O/sub 3/-KHF/sub 2/-H/sub 2/O/sub 2/-H/sub 2/O, where mixed water solutions of potassium bifluoride and hydrogen peroxide of different concentrations were employed as the crystallization medium. The mixed single-crystals based on antimony orthoniobate were studied on a URS-50 IM diffractometer. Analysis and comparison of the standard diffraction patterns of SbNbO/sub 4/ and the diffraction patterns of mixed samples of (Sb/sub 1-x/Bi/sub X/)NbO/sub 4/ showed that the latter are solid substitution solutions.
