Palladium

By Dong-A Special Metals, Inc.

What Is Palladium?

Palladium (symbol Pd, atomic number 46) is a rare, silvery-white precious metal belonging to the platinum group metals (PGMs). Soft, ductile, and corrosion-resistant, palladium is classified as a transition metal. It is typically extracted as a by-product of platinum or nickel-copper ore refining.

Despite its relatively low melting point (1,555°C), palladium shows excellent oxidation resistance. Most importantly, it has a unique ability to absorb and diffuse hydrogen at room temperature, making it vital for hydrogen storage and catalytic processes.


Industrial Applications of Palladium

Palladium plays an essential role in high-tech industries and emission control technologies:

- Catalytic converters: The largest demand comes from the automotive industry, where palladium acts as a catalyst to convert NOx, CO, and HC into less harmful substances. It is especially crucial for gasoline vehicles.

- Semiconductors and electronics: Thanks to its high electrical and thermal conductivity, high-purity palladium is widely used in electronic components.

- Hydrogen-related applications: Palladium's ability to absorb hydrogen supports its use in hydrogen sensors and storage systems.

- Precision alloys: Palladium easily forms workable alloys, making it suitable for complex mechanical parts.


Palladium Recycling: A Growing Market

With its limited global supply—mainly from Russia, South Africa, and Canada—palladium recycling has become a strategic focus:

- Recycling sources: Spent automotive catalytic converters, electronic waste, and industrial scrap.

- Market growth: The global palladium recycling market is expected to reach $1.5 billion by 2025, growing at a CAGR of 9%, far outpacing that of platinum.

- Strategic importance: Recycling reduces dependence on mining and strengthens supply chain stability.


Environmental and Economic Outlook

As global environmental regulations tighten, demand for catalytic converters rises—boosting palladium consumption. Despite the shift toward electric vehicles (EVs), internal combustion engine (ICE) vehicles will continue to require palladium, sustaining demand.

Palladium's unique properties and scarcity ensure its continued relevance in:

- Clean energy

- Automotive emissions control

- High-performance electronics

For nations and manufacturers, recycling and efficient use of palladium are now critical components of sustainable resource management.
