Electrochemical reaction and electrocrystallization of W in NaCl-KCl-NaF-Na2WO4 melts were investigated at 973K using cyclic voltammetry, chronopotentiometry and chronoamperometry. The electrochemical reaction process of W was a quasi-reversible process controlled by ion diffusion and electron transport. The electrocrystallization of W involved instantaneous hemispheroid three-dimensional nucleation, and the W ion diffusion coefficient was 2.543 x 10-5cm/s for a XNaCl:XKCl:XNaF: XNa2WO4 = 2:2:1:0.01 composition.
