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.
