High Temperature Electrochemical Synthesis of Tungsten Boride from Molten Salt

Article Preview

Abstract:

High temperature electrochemical synthesis of tungsten boride has been performed in KF-KCl melts with B2O3 and WO3 used as reactants at 1033K. The cathode product was investigated in the current density range 0.4A/cm2-0.6A/cm2 and characterized by means of XRD analyses and SEM. The results indicated that cathode product is mainly consist of W2B5 and WB4, the powders are fine (＜0.5um). Current density exert a great effect on the phase composition, particle size and morphology of the cathode product.
