Modeling of submicron complex oxides synthesis

Resumo

The results of our studies of the model of synthesis of barium titanate and nickel–zinc ferrite powders including the mutual influence of the micro and macro scales characteristic for the synthesis of submicron- and nanosized complex oxides were reported. The relationship between the structure of oxides and the synthesis conditions was studied. The characteristics of the gas-dynamic structure in the synthesis reactor, temperature fields, reagent concentrations, and synthesis products were obtained by kinetic calculations of the synthesis of barium titanate and nickel–zinc ferrite in a wide range of similarity parameters.
