Abstract

As one of the critical intermediate compounds of the sodium roasting converter slag, sodium pyrovanadate (Na4V2O7) powder was synthesized by solid-state reaction using NaCO3 and V2O5 as raw materials in this study. The preparation was first evaluated by thermodynamic software FactSage® with the minimum Gibbs free energy principle. Effect of temperature (T) and partial pressure of carbon dioxide P(CO2) was analyzed, and the results indicated that the reaction proceeds extensively with increasing temperature and reducing P(CO2). TG-DSC was applied to further characterize the preparation process, and it can be found that the reaction proceeds extensively near 540 °C corresponding to carbon dioxide gas escaping. Non-isothermal kinetics with a single scan rate was applied to the solid-state reaction, the average apparent activation energy was obtained using Freeman–Carroll method, equal to 102 ± 6 kJ/mol by mathematic fitting. In addition, XRD further verified the phase composition of Na4V2O7, and a large number of voids were detected from SEM images caused by the gas release.
