Description

Palladium CAS NO 7440-05-3 is a lustrous, silvery-white transition metal belonging to the platinum group, prized for its exceptional catalytic properties, corrosion resistance, and ductility. Its unique ability to absorb large volumes of hydrogen and facilitate a wide range of chemical transformations makes it indispensable in modern industrial chemistry and manufacturing. This high-value metal is a critical raw material for the automotive, electronics, chemical synthesis, and jewelry sectors, where performance and reliability are paramount.

Application

• Automotive Catalysts: Primary component in catalytic converters for gasoline and hybrid vehicles to reduce harmful emissions (CO, NOx, hydrocarbons).
• Electronics & Electrical: Used in multilayer ceramic capacitors (MLCCs), connector platings, and hybrid integrated circuits due to its excellent conductivity and solderability.
• Chemical Processing & Catalysis: Serves as a highly active catalyst for hydrogenation/dehydrogenation reactions, carbon-carbon coupling (e.g., Suzuki, Heck reactions), and petroleum refining.
• Dental & Medical Alloys: A key alloying element in dental crowns, bridges, and certain medical devices for its biocompatibility and strength.
• Jewelry & Watchmaking: Used in white gold alloys and as a pure, hypoallergenic precious metal for fine jewelry and luxury timepieces.
• Hydrogen Technologies: Essential for hydrogen purification, storage, and sensing applications due to its selective hydrogen permeability.
• Investment & Finance: Traded as bullion (bars, coins) and in exchange-traded funds (ETFs) as a precious metal commodity.

Quality Control

Our palladium is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. We supply various grades, including industrial (99.95%) and high-purity (99.99%+) specifications, tailored for catalytic or electronic applications. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing assay results and impurity profiles (e.g., Pt, Rh, Fe, Pb). Our quality systems support compliance with relevant industry standards and traceability requirements.

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 oxidizing agents, and halogenated compounds. For powdered forms, appropriate measures should be taken to prevent dust formation and accumulation.
