Potassium silver cyanide is irritating to the skin and mucous membranes. Lacrimation (tearing) and a burning sensation of the mouth and throat are common. Excessive salivation, nausea, and vomiting may also occur. Emergency Life-Support Procedures: Acute exposure to potassium silver cyanide may require decontamination and life support for the,
CN1161935A - Method for production of silver potassium,
A new method for production of potassium argentocyanide is to use the basic material or base-releasing materiol to neutralize silver nitrate solution, then the neutrolizes silver nitrate solution is added to potassium cyanide solution to directly precipitate silver cyanide, and finally, silver cyanide reacts again with potassium cyanide to obtain potassium argentocyanide.

Silver Plating - STERC
Silver is plated from alkaline cyanide solutions almost exclu-sively. The metal is introduced as potassium silver cyanide, KAS(CN) 2, which forms when silver anodes dissolve in potassium cyanide solution. Plating solutions usually contain between 10 to 40 g/L (1.3 to 5.3 oz/gal) silver metal and up to 120 g/L (16 oz/gal) free potassium cyanide,
Potassium Cyanide - Structure, Properties, Preparation,
Potassium cyanide is a highly toxic inorganic substance with the general formula KCN. It is generally prepared by the reaction of hydrogen cyanide (HCN) and potassium hydroxide (KOH). This is made up of a solid base (KOH) and a weak acid (HCN). This is used for the extraction of gold, silver, and other metals.

Synthesis of silver cyanide without poisonous KCN or NaCN,
Highly crystalline silver cyanide (AgCN) was synthesized at room temperature using acetonitrile (CH 3 CN) as a source of cyanide ion (CN −).The in-situ generation of CN − was assisted by the C CN bond breaking of CH 3 CN. The reaction was found to be catalyzed by vanadium pentoxide (V 2 O 5) and hydrogen peroxide (H 2 O 2).The process was very simple and effective one as
