ELECTROLYTIC METHOD OF PRODUCING ULTRAFINE CERIUM HEXABORIDE POWDER Russian patent published in 2012 - IPC C01B35/04 C25C5/04 C01F17/00 

FIELD: chemistry.

SUBSTANCE: invention relates to electrolytic methods of producing pure cerium hexaboride. The cerium source used is 1-4 wt % anhydrous cerium chloride, the boron source is 1-3 wt % potassium fluoroborate and the background electrolyte is a eutectic mixture of potassium, sodium and cerium chlorides, which makes up the balance amount. Synthesis of ultrafine cerium hexaboride powder takes place via electrolysis from a eutectic melt of KCl-NaCl-CsCl, which contains cerium chloride and potassium fluoroborate.

EFFECT: invention enables to obtain a pure end product owing to good solubility of the eutectic background electrolyte in water and reducing power consumption by reducing synthesis temperature.
