Potassium dicyanoaurate Chemical Properties,Usage,Production

Chemical Properties

White, crystalline powder. Soluble in water; slightly soluble in alcohol; insoluble in ether.

Uses

Electrogilding.

Uses

Potassium dicyanoaurate is a gold salt used in the electroplating industry.

Uses

Gold potassium cyanide is an important gold source used in electrolytic gold plating. The primary application of gold potassium cyanide is in the electroplating of metals. In addition, gold potassium cyanide is also used in the decorative plating of jewelry. It is useful for photoreduction of gold ions using the ZnO nanopowder. It is useful for the preparation of gold-gold junction electrode in the voltammetric glucose detection.

Hazard

Highly toxic.
