Lanthanum carbonate

La₂(CO₃)₃

Lanthanum carbonate

Lanthanum is a key input in fluid catalytic cracking (FCC), enhancing efficiency and reducing the environmental impact of petroleum refining—particularly for high-performance jet fuels. Beyond refining, it plays an essential role in the production of nickel-metal hydride (NiMH) batteries and supports innovation in advanced optical lenses and vision systems.

Product details

Lanthanum powers cleaner refining and advanced technologies, enhancing efficiency while enabling innovations.

Domestic Production & Supply

Sourced from California’s Mountain Pass Rare Earth Mine and Processing Facility, our lanthanum carbonate is produced with a focus on responsible operations and environmental stewardship. Once reliant on imports, the United States now benefits from MP Materials’ ability to fulfill a significant portion of domestic demand.

High-Performance Chemistry

Our refined lanthanum carbonate is engineered to meet the exacting specifications required by FCC catalyst formulators at high purity (99% La/TREO). This focus on consistent quality ensures optimal performance, efficiency, and reliability across a broad range of applications.

Stringent Quality Assurance

In-process sampling, testing, and analysis at MP’s on-site Analytical Laboratory ensure that every batch of lanthanum carbonate aligns with customer standards. ISO 9001-certified quality management protocols guide our operations, maintaining confidence and consistency from production through delivery.

Available at scale

Our U.S.-based production and logistics capabilities are designed to meet the needs of domestic customers seeking a secure, readily available source of lanthanum carbonate. We are well-equipped to fulfill large-scale commitments—ranging from 200 MT to 1,000 MT or more—providing consistent quality, predictable lead times, and the stability essential for long-term planning.
