Potassium Tetracyanoaurate(III)
Industrial Applications
Potassium Tetracyanoaurate(III) is an important gold coordination compound primarily used in electroplating and surface finishing industries. It serves as a stable source of gold ions for gold electroplating baths, where it enables the deposition of uniform, high-purity gold coatings onto metals and electronic components. These gold coatings are valued for their excellent electrical conductivity, corrosion resistance, and aesthetic appearance. Potassium Tetracyanoaurate(III) is also used in research and specialty chemical manufacturing as a precursor for the synthesis of other gold compounds and coordination complexes.
Physical Properties
Potassium Tetracyanoaurate(III) is an inorganic coordination compound that typically appears as a yellow to orange crystalline solid. It is soluble in water, forming clear solutions suitable for electrochemical and plating applications. The compound contains gold in the +3 oxidation state coordinated by four cyanide ligands, giving it good chemical stability under controlled conditions. It is non-volatile and stable when stored properly, though it should be handled with care due to the presence of cyanide ligands.
