Abstract: By atomic parameters and pattern recognition method, the regularities of the formability of intermediate compounds in M2O3-M′2O3 oxide systems were studied, and the criteria were obtained. It was found that the formation and its chemical formula of complex oxide are chiefly determined by the positive ionic radii of its constituent elements. The predicted results of six M2O3-M′2O3 systems were in agreement with the experiments.
