Used as a catalyst in organic synthesis, particularly in the polymerization of esters and other monomers, enhancing reaction efficiency and selectivity. It is also employed in the production of advanced materials, such as ceramics and glass, where it improves thermal stability and optical properties. In the field of electronics, it serves as a precursor for depositing lanthanum-based thin films, which are essential in capacitors and other electronic components. Additionally, it finds application in environmental chemistry for the removal of phosphates from wastewater, aiding in water purification processes.
