Description

Zinc Cyanide is an inorganic salt of significant industrial importance, primarily valued for its role as a key reagent in electroplating and metal finishing processes. Its controlled reactivity makes it a critical component for creating durable, corrosion-resistant coatings on various metal substrates. This high-purity chemical is essential for manufacturers in the electroplating, metallurgy, and specialty chemical synthesis sectors seeking reliable and consistent performance.

Application

• Electroplating: A primary source of cyanide ions in zinc, cadmium, copper, brass, and precious metal plating baths for corrosion protection and decorative finishes.
• Metal Surface Treatment: Used in immersion plating and as a surface activator to prepare metals for subsequent coating or bonding processes.
• Chemical Synthesis: Serves as a reagent in organic synthesis for the introduction of the cyano group and in the preparation of other metal cyanides.
• Gold & Silver Extraction: Historically used in the cyanidation process for the extraction of gold and silver from ores, though largely replaced by sodium cyanide.
• Fumigant Production: A component in the manufacture of certain fumigants and insecticides.
• Laboratory & Research: Utilized as a standard or reagent in analytical chemistry and materials science research.
