General description

Potassium dicyanoaurate, also known as potassium gold cyanide. It is a water-soluble salt that is commonly used in gold electroplating, as a precursor for the synthesis of other gold compounds, and in certain chemical processes.

Application

Potassium dicyanoaurate(I) can be used as:     
  • A precursor in the synthesis of gold nanoparticles and nanowires, which are crucial for applications in electronics, photonics, and catalysis     
  • An electrolyte in the potentiostatic deposition of gold nanowires, which are used in electronics and photonics.    
  • A key component in the production of conductive inks and coatings, which are essential for printed circuit boards and other electronic components.
  • A catalyst in certain chemical reactions.
