X-ray diffraction, differential thermal analysis, polarized light microscopy, and dielectric measurements have been used to study phase transitions and solid solutions in the K{sub 3}MO{sub 3}F{sub 3}-A{sub 3}MO{sub 3}F{sub 3} (A = Rb, Na; M = Mo, W) systems. K{sub 3}MO{sub 3}F{sub 3}-Na{sub 3}MO{sub 3}F{sub 3} (M = Mo, W) systems show two solid solutions; the first (SSI) near x - 0 (K{sub 3-x}Na{sub x}MO{sub 3}F{sub 3}) involves only one transition at T{sub c} which is practically independent of composition. The sharp transition at T{sub 1}(
