GILDING ELECTROLYTE COMPOSITION AND METHOD OF ITS PRODUCTION Russian patent published in 2013 - IPC C25D15/00 

FIELD: metallurgy.

SUBSTANCE: proposed electrolyte contains the following components per 1000 mae parts potassium dithyanoaurate - 5-22; citric potassium - 30-95; brilliance-forming additive - 0.5-5; superdispersed diamond - 10-42; superdispersed silicon oxide - 80-90, water making the rest. To prepare electrolyte, preset amounts of potassium dithyanoaurate, citric potassium and brilliance-forming additive are dissolved in half the calculated amount of distilled water. Then, aqueous solution of superdispersed diamond is added to obtained solution and mixed to add remaining amount of distilled water. If required, pH is corrected to 3.6-3.8 to add thereafter aforesaid superdispersed silicon oxide.

EFFECT: in five year storage no sedimentation of components is observed.
