Abstract. The paper presents a computational and experimental study of the interaction of reagents in the system (48 mol.% Li2WO4–52 mol.% Na2WO4)eut–MgCl2 based on thermodynamic and physical-chemical analysis over a wide range of temperatures. The implementation of interaction reactions in a molten mixture significantly reduced energy consumption, lowered the synthesis temperature, and increased the rate of magnesium tungstate production. Based on the Temkin-Shvartsman method and the Van’t Hoff isotherm equation for chemical reactions, the thermodynamic probability of the reaction underlying the synthesis of magnesium tungstate was estimated. It has been established that all exchange processes proceed with high negative Gibbs energies, which indicates the irreversibility of the reaction between lithium and sodium tungstates and magnesium chloride. The synthesis of magnesium tungstate in the molten system (Li2WO4–Na2WO4)eut–MgCl2 is characterized by high productivity and yield of the target product. The analysis and diagnostics of the synthesized magnesium tungstate samples were carried out using the X-ray phase method (D2 Phazer, manufacturer Bruker AXS, Germany), and the dispersion was determined using a scanning electron microscope (Tescan VEGA3LMH produced by Tescan, Czech Republic).
