Phase relationship in the [(K1/2Bi1/2)1-y (Na1/2Bi1/2)y ](Ti1-x Bx )O3 system with B=Zr, Fe1/2Nb1/2, Zn1/3Nb2/3 or Mg1/3Nb2/3 has been investigated by dielectric measurement and X-ray diffractometry. All of the bi-binary systems were solid-soluble throughout the entire composition range. With increasing y and x, ferroelectric Curie point decreased and the ε-T curve became flat. Composition dependence of the transition temperature was examined by varying x or y. Phase diagrams were mostly determined at room temperature on square diagrams except for a restricted area in the vicinity of (Na1/2B1/2)ZrO3, which involved a tetragonally distorted phase and could not be accounted for. The ferroelectric tetragonal phase was confined within a narrow range of x<0.1 and the rhombohedral phase was dominant in all of the systems studied here.
