Palladium Advantages

• Excellent ductility and plasticity: Palladium boasts one of the best ductilities among all metals, allowing it to be processed into extremely thin sheets (with thicknesses in the micrometer range), making it ideal for the fabrication of precision components.
• High melting point and thermal stability: It maintains stable physical properties at high temperatures, making it suitable for operations up to 500°C, such as in hydrogen separation processes.
• Lightweight characteristics: With a density of 12.02 g/cm³, palladium is approximately 78% lighter than platinum per unit volume, giving it a clear advantage in applications where weight is a critical factor.
• Outstanding hydrogen adsorption and transport capabilities: It efficiently separates ultra-high-purity hydrogen from mixed gases.
• Superb chemical stability: It is resistant to oxidation at room temperature and possesses strong corrosion resistance. It can withstand the erosion of many chemical substances and remains stable in acidic or oxidative environments, making it ideal for long-term experimental use.
• Highly efficient catalytic properties: As an excellent catalyst, palladium exhibits unique catalytic activity and selectivity, enabling it to accelerate chemical reactions without being consumed itself.
• Good biochemical compatibility: Palladium can be used in dental materials, medical devices, as well as in biomedical research areas such as biosensing and drug delivery systems.

Process

(1) Raw material purification: Palladium concentrate or waste is refined and chemically purified into high-purity palladium ingots or palladium blanks.

(2) Melt casting and opening billets: melting ingots under vacuum or inert atmosphere, and then forging or hot rolling into thick slabs.

(3) Multi-pass cold rolling: through repeated cold rolling, the thickness is gradually reduced to obtain different specifications of palladium foil intermediates.

(4) Intermediate annealing: Vacuum annealing is interspersed during the cold rolling process to eliminate work hardening and ensure plasticity and facilitate continued rolling.

(5) Precision rolling: Achieve the target thickness through precision cold rolling, and control the flatness and thickness tolerance.

(6) Cutting and slitting: shearing, slitting, and punching according to size requirements to make sheets or rolls.

(7) Final heat treatment: vacuum annealing adjusts the hardness and mechanical properties, and is divided into soft/semi-hard/hard finished products.

(8) Cleaning treatment: degreasing, pickling, rinsing with pure water, drying, removing oil stains, and oxide layers.

(9) Testing and packaging: testing the size, surface, purity, and performance, and packaging it in a vacuum or inert gas after qualification.
