Abstract:ANN-atomic parameter method was used in investigating the regularity of the melting point of MM'O3 type intermediate compounds. A method for the prediction of the melting points of MM'O3 type intermediate compounds was proposed. And three atomic parameters of constituent elements, ionic radii Ri, electronegativity X, covalent radii Rc and the known melting points data of MM'O3-type compounds were used to find a mathematical model for the melting point prediction, with ANN as the method of computation. The predicted results agree well with the experimental ones.
