Description

Gold(I) Cyanide is a key inorganic gold compound essential for high-precision electroplating and surface finishing processes. This material matters for its ability to deposit high-purity, corrosion-resistant gold coatings with excellent electrical conductivity and solderability. It is primarily needed by manufacturers in the electronics, semiconductor, and jewelry industries, as well as for specialized chemical synthesis and catalysis.

Application

• Electroplating & Surface Finishing: Primary reagent for high-purity gold electroplating of connectors, contacts, and printed circuit boards (PCBs).
• Semiconductor Manufacturing: Used in the deposition of gold layers for wire bonding and chip packaging.
• Jewelry & Decorative Plating: Provides a bright, tarnish-resistant finish for luxury items and decorative components.
• Chemical Synthesis: Serves as a precursor for other gold complexes and organometallic compounds in research and development.
• Catalysis: Employed in the preparation of catalysts for specialized organic reactions.
• Medical Device Coating: Used for biocompatible gold coatings on certain medical implants and instruments.

Quality Control

Our Gold(I) Cyanide is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed for critical parameters including gold content and cyanide ion concentration. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under dry conditions. It is also easily oxidized and should be stored away from strong acids, fluorides, and strong alkalis.
