FIELD: metallurgy.
SUBSTANCE: Anhydrous gadolinium trichloride is used as gadolinium 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 potential of - 2.6 to -2.8 V relative to glass-carbon quasi-stationary comparison electrode.
EFFECT: obtaining pure ultrafine powder of gadolinium hexaboride; increase in synthesis rate of target product from molten electrolyte and reduction of costs.
