FIELD: metallurgy.
SUBSTANCE: invention relates to electrolytic methods for obtaining pure dysprosium hexaboride. Anhydrous dysprosium trichloride is used as dysprosium source, potassium fluoroborate is used as boron source, and equimolar mixture of potassium and sodium chlorides is used as base electrolyte. Electrolysis is carried out in potentiostatic mode at temperature of 700±10°C, current densities of 0.1 to 1.0 A/cm2 and electrolysis potentials of 2.5 to 2.8 V relative to glass-carbon quasi-stationary comparison electrode.
EFFECT: obtaining pure ultrafine powder of dysprosium hexaboride; increase in synthesis rate of target product from molten electrolyte and reduction of power consumption.
