1. Potassium dicyanoaurate is based on the special properties of gold plating, which is widely used in industrial and decorative fields. Among them, industrial gold plating is mostly used in electronic information industries such as printed circuit boards, connectors, and semiconductor devices; decorative gold plating is widely used in jewelry. Jewelry, watches, musical instruments, handicrafts, hardware parts and other fields.
2.Potassium dicyanoaurate is widely used in high-tech fields such as electronics, information, aerospace, and aviation.
3. In addition to being used for gold plating, potassium dicyanoaurate is also used as an analytical reagent and in the pharmaceutical industry. At present, there is no national standard for potassium gold cyanide products, and the quality of potassium gold cyanide products produced by various manufacturers varies greatly.
