We aim to provide a comprehensive overview for manufacturers, engineers, and business leaders.

What are Platinum Group Elements?

Platinum group elements (PGEs) refer to a group of six chemically similar metallic elements: platinum (Pt), palladium (Pd), rhodium (Rh), ruthenium (Ru), iridium (Ir), and osmium (Os). These elements share characteristics such as high density, high melting points, and exceptional resistance to corrosion and oxidation. They are also known for their remarkable catalytic properties, meaning they can significantly speed up chemical reactions without being consumed in the process. This unique combination of traits makes them invaluable across a wide spectrum of industrial applications. The rarity of PGEs, coupled with the complex processes required for their extraction and refining, contributes to their high economic value. They are typically found together in the Earth’s crust, often associated with nickel and copper ore deposits. Their geological scarcity and specialized uses place them among the most important strategic metals for advanced economies, particularly in the United States, where innovation drives demand. The year 2026 sees an ongoing need for these metals as new technologies emerge and existing ones advance.

The Six PGEs and Their Properties

Each of the six platinum group elements possesses distinct characteristics that lend themselves to specific uses:

Platinum (Pt): Renowned for its excellent catalytic activity, high melting point, and resistance to corrosion. It is widely used in catalytic converters, jewelry, chemical processing, and medical implants.

Palladium (Pd)

Palladium is a highly effective catalyst, particularly in organic chemistry, and is crucial for automotive catalytic converters, electronics (especially in multilayer ceramic capacitors), dentistry, and jewelry. Its ability to absorb large amounts of hydrogen also makes it vital for purification and fuel cell technologies.

Rhodium (Rh)

Rhodium is exceptionally reflective and resistant to corrosion, making it ideal for plating automotive catalytic converters to reduce harmful emissions. It is also used in high-temperature applications, specialized mirrors, and jewelry.

Ruthenium (Ru)

Ruthenium is a hard, corrosion-resistant metal that enhances the properties of other metals, particularly platinum and palladium. It’s used in electrical contacts, catalysts, and has emerging applications in cancer treatment and advanced electronics.

Iridium (Ir)

Iridium is the most corrosion-resistant metal known and has an extremely high melting point. It’s used in high-temperature applications, spark plugs for aircraft engines, and in medical devices.

Osmium (Os)

Osmium is the densest naturally occurring element and is rarely used in its pure form due to its brittleness and toxicity. It is sometimes alloyed with other platinum group metals to increase hardness, finding niche applications in electrical contacts and fountain pen nibs.

Key Platinum Group Elements Uses in San Jose Industries

San Jose, the undisputed capital of Silicon Valley, is a hub for innovation and technology, industries that are profoundly dependent on the unique properties of platinum group elements (PGEs). The city’s thriving sectors, including electronics manufacturing, automotive technology development, and advanced materials research, all rely heavily on these precious metals. Understanding the specific applications of PGEs within these domains is crucial for businesses operating in or supplying to the San Jose region. Their use in catalytic converters, electronic components, and advanced chemical processes underpins much of the technological progress seen in this dynamic area of the United States.

Automotive Catalysis: The most significant use of platinum and palladium is in catalytic converters, which reduce harmful emissions from vehicle exhausts. While San Jose itself is a major center for automotive R&D and electric vehicle innovation, the demand for these metals remains high globally, influencing supply chains that connect to the region.

Electronics Manufacturing

The electronics industry, a cornerstone of San Jose’s economy, utilizes PGEs extensively. Palladium, in particular, is crucial for multilayer ceramic capacitors (MLCCs) found in virtually all electronic devices. Platinum and rhodium are used in high-reliability electrical contacts and connectors due to their resistance to corrosion and stable electrical properties. Iridium’s hardness and corrosion resistance make it suitable for specialized components in advanced electronic systems. As electronic devices become smaller, more powerful, and more complex, the demand for these high-performance materials only intensifies, directly impacting manufacturers in and around San Jose.

Chemical and Petrochemical Industry

PGEs are indispensable catalysts in various chemical and petrochemical processes. Platinum and palladium are used in the production of nitric acid, a key component in fertilizers and explosives. Rhodium is used in processes like hydrogenation and isomerization. Ruthenium is employed in certain organic synthesis reactions. The chemical industries that support or are integrated with San Jose’s high-tech manufacturing often rely on these catalytic capabilities for efficiency and product purity. The development of new chemical compounds and materials, a constant in San Jose’s R&D landscape, frequently involves PGE catalysts.

Medical and Healthcare Applications

The medical sector also benefits significantly from PGEs. Platinum’s biocompatibility and inertness make it ideal for use in pacemakers, neurostimulators, and chemotherapy drugs (like cisplatin). Palladium is used in dental alloys and certain medical instruments. Iridium’s high density and radiopacity are useful in medical imaging and brachytherapy seeds. As San Jose continues to foster advancements in biotechnology and medical technology, the demand for these specialized applications of PGEs is projected to increase. Innovations in 2026 are likely to see further integration of these materials into life-saving devices and treatments.

Jewelry and Investment

While not a primary industrial use driving demand in San Jose’s tech sector, platinum and palladium are also highly valued in the jewelry industry for their luster, durability, and rarity. They are also considered investment metals, sought after by individuals and institutions for their store of value. This aspect contributes to their overall market dynamics, which indirectly affect industrial availability and pricing for manufacturers in the region.

Emerging Applications and Future Trends for PGEs
