A method was developed for the determination of a region of compositional fluctuation in the perovskite ternary solid‐solution system PhZrO 3 ‐PbTiO 3 ‐Pb(Mg 1/3 Ta 2/3 )O 3 . The compositional fluctuation in the ternary system extends two‐dimensionally on the phase diagram. The method described in this paper utilized the fact that the compositional fluctuation region abuts on the curves of composition whose lattice spacing is the lower or higher fluctuation limit. The fluctuation limits of the lattice spacings were estimated from X‐ray diffraction analysis.
