Favored by various factors, the development trend of silver potassium cyanide industry is improving

Potassium silver cyanide, also known as potassium silver cyanide, is an inorganic compound with the chemical formula K[Ag(CN)2]. It appears as a white crystalline powder at room temperature. It is soluble in water and alcohol and is highly toxic to humans. It is light sensitive and will generate hydrocyanic acid and corresponding silver compounds when exposed to acid.

There are various methods for producing potassium silver cyanide. There are three common methods. They are the electrolysis method, which refers to using pure silver as the anode and cyanide solution as the electrolyte. After direct current is passed, the silver dissolves from the anode and combines with CN-, and then through The method of generating potassium silver cyanide by taking out the electrolyte, concentrating and crystallizing, etc.; the direct method refers to the method of using silver nitrate and potassium oxide as raw materials, and obtaining silver potassium cyanide through concentration and crystallization; the indirect method refers to using pure silver or crude silver as potassium cyanide. Silver is used as raw material, and intermediate products such as silver nitrate, silver chloride, and silver cyanide are first generated, and then react with potassium cyanide to generate potassium silver cyanide. Among them, the electrolysis method is currently the most rapidly developed and widely used method for silver potassium cyanide.

According to the“China Silver Cyanide Potassium Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that potassium silver cyanide has the advantages of good solderability of the coating, high surface finish, and strong bonding with the substrate. It has gradually replaced traditional silver nitrate, silver chloride, and silver carbonate as the main component required for silver plating and alloy processes. Raw material silver salt. At this stage, the silver plating process has been widely used in electrical appliances, electronics, instruments, mechanical equipment, lighting fixtures, communication devices, aerospace and other manufacturing industries. With the rapid development of the manufacturing industry, the continuous expansion of silver plating process application scenarios has driven the development of silver cyanide. Potassium requirements are constantly increasing.

The current global silver potassium cyanide production capacity is mainly concentrated in China, Germany, South Africa, Switzerland, Japan and other countries. Major companies include Switzerland’s Metalor Technology, Germany’s Heraeus, the UK’s Johnson Matthey, South Korea’s MK Electronics, Japan’s Tanaka Precious Metals and China Yantai Zhaojin Lifu Precious Metals, Suzhou Xingrui Precious Metal Materials, Jiangsu Suda Specialty Chemicals, Shenzhen Fujun Materials Technology, Dongguan Dongwu Highly Toxic Chemicals, Ningbo Fenghua Ruixin Environmental Protection, Sanmenxia Tiancheng Chemical, Koyang Chemical Applied Materials, etc.

From the perspective of the domestic market, the number of silver potassium cyanide companies in my country is constantly increasing. In the context of continuous improvement of corporate technology, some companies already have advantages in technology, scale, and product quality, and their competitiveness is gradually strengthening. In the future, local companies are expected to compete in the global market. Occupying more shares, the industry has huge development potential.

Industry analysts said that my country’s silver potassium cyanide production technology is currently being upgraded, such as diaphragm electrolysis The emergence and application; market demand is increasing. Silver potassium cyanide can be widely used in silver plating and its alloy processes. The terminal applications involve electronics, communications, aviation and other fields. The rapid development of the downstream market has driven its demand to continue to increase; enterprises The number is increasing and the competitiveness is increasing. Overall, the development of my country’s silver potassium cyanide industry continues to be favored by many factors, and the overall development trend is positive.
