Description

Platinum CAS NO 7440-06-4 is a precious transition metal known for its exceptional catalytic activity, high density, and outstanding resistance to corrosion. Its unique properties make it indispensable for accelerating critical chemical reactions and enabling advanced technologies. This material is essential for manufacturers and researchers in the chemical processing, automotive, electronics, and medical device industries.

Application

• Catalyst Production: Primary component in heterogeneous catalysts for nitric acid production, petroleum refining (catalytic reforming), and silicone manufacturing.
• Automotive Industry: Key material in catalytic converters for diesel and gasoline engines to reduce harmful exhaust emissions (CO, NOx, hydrocarbons).
• Electronics & Electrical: Used in high-reliability electrical contacts, electrodes, spark plugs, and resistance thermometers due to its stability and conductivity.
• Medical & Biomedical: Critical for implantable devices (pacemakers, stents), anti-cancer drugs (cisplatin, carboplatin), and laboratory equipment.
• Jewelry & Investment: High-purity platinum is used in fine jewelry, bullion, and as a financial investment commodity.
• Glass Manufacturing: Used in the production equipment for optical fibers and high-quality glass due to its non-reactive nature at high temperatures.
• Hydrogen Economy: Serves as a crucial catalyst in proton exchange membrane (PEM) fuel cells and electrolyzers for green hydrogen production.
• Laboratory & Analytical: Used in crucibles, electrodes for electrochemistry, and standards for analytical instruments.

Quality Control

Our platinum is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide material with typical purities ranging from 99.95% to 99.999% (5N), suitable for industrial, electronic, and catalytic applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing assay and impurity profiles via techniques like ICP-OES/MS. We can supply material compliant with various in-house specifications and support customer-specific quality audits.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids, strong oxidizers, and incompatible materials. For high-surface-area forms like platinum black or sponge, store under an inert atmosphere to minimize surface oxidation.
