Uses & Applications

Applications and End-Uses for Lanthanum

Lanthanum (La) is a high-criticality rare earth element with annual global production of approximately 40,000 tonnes REO. Lanthanum is a light rare earth element widely used in petroleum cracking catalysts, optical glass, and nickel-metal hydride batteries for hybrid vehicles. It is one of the more abundant rare earths and the namesake of the lanthanide series. Lanthanum-based compounds are also used in water treatment to remove phosphates and in specialty ceramics.

Key Applications

The primary end-uses of Lanthanum span multiple sectors. The following applications represent the most significant sources of global demand:

• Petroleum refining catalysts - Key alternatives include Cerium, neodymium (partial). Lanthanum provides optimal performance in FCC catalysts but other rare earths can partially substitute with some activity loss
• Hybrid vehicle batteries (NiMH) - Lanthanum is valued in hybrid vehicle batteries (nimh) for its unique physical and chemical properties that are difficult to replicate with alternative materials.
• Camera and telescope lenses - Lanthanum is valued in camera and telescope lenses for its unique physical and chemical properties that are difficult to replicate with alternative materials.
• Hydrogen storage alloys - Lanthanum is valued in hydrogen storage alloys for its unique physical and chemical properties that are difficult to replicate with alternative materials.
• Phosphors for lighting - Lanthanum is valued in phosphors for lighting for its unique physical and chemical properties that are difficult to replicate with alternative materials.

Product Forms and Specifications

Lanthanum is commercially available in 4 primary product forms, each serving different industrial requirements:

Demand Outlook

Lanthanum appears on both the USGS Critical Minerals List and the EU Critical Raw Materials List, underscoring its strategic importance across Western economies. Growing demand from electrification, digitalization, and defense modernization is expected to place additional pressure on the Lanthanum supply chain through the end of this decade.
