ELECTROLYTIC METHOD OF PRODUCING ULTRAFINE GADOLINIUM HEXABORIDE POWDER Russian patent published in 2014 - IPC C25C5/04 C01B35/04 C01F17/00 

FIELD: chemistry.

SUBSTANCE: powder is synthesised by electrolysis from a molten medium which includes gadolinium chloride and calcium fluoroborate in a background electrolyte at temperature of 550±10°C in an atmosphere of purified and dried argon. The background electrolyte used is a eutectic mixture of potassium, sodium and caesium chlorides, with the following ratio of components, wt %: gadolinium chloride 3.0-7.0, potassium fluoroborate - 6.0-10.0, eutectic mixture of potassium, sodium and caesium chlorides - the balance.

EFFECT: invention enables to obtain pure ultrafine gadolinium hexaboride powder, increases the rate of synthesis of the end product from a molten electrolyte and reduces power consumption.
