Application areas：
Sodium cyanide is an important basic chemical raw material used in basic chemical synthesis, electroplating, metallurgy and organic synthesis of medicines, pesticides and metal processing. Complexing agent, masking agent. Refining and electroplating of precious metals such as gold and silver.
Used as quenching agent for various steels in the machinery industry.
In the electroplating industry, it is used as the main component of copper, silver, cadmium and zinc plating. In the electroplating solution, it can reduce the anode polarization, ensure the normal dissolution of the anode, stabilize the plating solution, and improve the cathode polarization to obtain a uniform coating.
In the metallurgical industry, it is used to extract precious metals such as gold and silver.
In the chemical industry, it is a raw material for manufacturing various inorganic cyanides and hydrocyanic acid. It is also used to manufacture copolymers of organic glass, various synthetic materials, nitrile rubber , and synthetic fibers.
In the dye industry, it is used to make cyanuric chloride (reactive dye intermediate and raw material for the production of brighteners).
In the pharmaceutical industry, it is used to manufacture methyl cyanoacetate and diethyl malonate . It is used as a mordant in the textile industry and is also used in liquid carburizing and nitriding of steel.
