APPLICATIONS
Glass & Optical Applications: Lanthanum micron powder is widely used in the production of infrared-absorbing glass, optical filters, and high-performance lenses. Its high refractive index and low dispersion make it ideal as a dopant in camera, microscope, and telescope lenses, enhancing clarity and chromatic correction in precision optics.
Ceramics & Specialty Materials: Lanthanum is incorporated into advanced ceramic formulations to improve thermal stability, dielectric properties, and mechanical strength. It supports applications in capacitors, piezoelectric devices, and high-temperature structural ceramics.
Metallurgy & Alloying: Lanthanum powder is used as an additive in high-strength low-alloy steels and non-ferrous alloys, where it acts as a grain refiner, deoxidizer, and impurity scavenger. It enhances mechanical properties and corrosion resistance in aerospace, automotive, and structural components.
Catalysis & Petrochemical Industry: Lanthanum plays a key role in fluid catalytic cracking (FCC) processes in petroleum refining. It improves catalyst stability and activity, enabling efficient conversion of heavy hydrocarbons. It also supports oxidation, hydrogenation, and dehydrogenation reactions in fine chemical synthesis.
Electronic & Energy Applications: Lanthanum compounds derived from micron powder are used in nickel-metal hydride (NiMH) batteries, solid oxide fuel cells (SOFCs), and electroceramics. Its ionic conductivity and thermal resilience contribute to energy storage and conversion technologies.
