A new method for determining the two-dimensional compositional fluctuation region in a ternary solid solution Pb{(Zr_xTi_<1-x>)_<1-y>(Mg_<1/3>Nb_<2/3>)_y}O_3 (PZTMN) was developed. Problems in determining the compositional fluctuation region in the previously-reported method, where fluctuations in x and those in y can be determined independently, are discussed. In this new method, diagrams of equal lattice spacing lines in the ternary system were prepared for various diffraction planes. The fluctuation limits of lattice spacing of these planes were determined by X-ray diffraction analysis. Lines of compositions of which lattice spacing is the fluctuation limit were drawn in the ternary diagram. The compositional fluctuation region is seen to abut on all these lines.
