Lanthanum Acetate, is mainly applied in specialty glass, water treatment and catalyst. Lanthanum compounds have numerous applications as catalysts, additives in glass, carbon lighting for studio lighting and projection, ignition elements in lighters and torches, electron cathodes, scintillators, GTAW electrodes, and others. Small amounts of Lanthanum added to steel improves its malleability, resistance to impact, and ductility, whereas addition of Lanthanum to Molybdenum decreases its hardness and sensitivity to temperature variations. Small amounts of Lanthanum are present in many pool products to remove the phosphates that feed algae.
Lanthanum(III) acetate sesquihydrate is used in specialty glass and in water treatment. It is used in the preparation of phenolate-bridged dilanthanum(III) complex, which is considered as a model for metalloproteins in applied chemistry. Further, it is used to prepare nanoparticulate porous lanthanum oxyfluoride (LaOF) films.
