    摘要: Compositions for electrodepositing silver, comprising a soluble silver compound, a non-cyanide electrolyte and selected organic phosphonate compounds, are described. These are stable for prolonged periods and are capable of depositing silver at relatively high rates without the need for soluble silver electrodes or cyanide replenishment to the bath, in contrast to conventional procedures.
