Lanthanum Oxide (La2O3) is a dense, white, high-purity rare earth compound recognized for its high melting point, high refractive index, and high dielectric constant (k). Chemically a basic ceramic, reacting slowly with water to form the hydroxide and possessing a strong affinity for carbon dioxide and phosphate ions. Lanthanum(III) oxide's electronic structure makes it indispensable in advanced materials. The compound's versatility spans electronics, optics, and specialty chemical applications. In (Catalysis), it enhances thermal stability and acts as a promoter for complex chemical transformations. In (Optics), it reduces chromatic aberration and enhances light transmission. Aside from this, its powerful Laßt ion, released in acidic conditions, functions as an effective, life-saving phosphate binder in medical treatments. Also referred to as ‘Dilanthanum trioxide’ and ‘Lanthanum Sesquioxide’ by lanthanum oxide suppliers and lanthanum oxide manufacturers, respectively. We are the leading, trusted lanthanum oxide worldwide and in the United States, with reliable lead times and global supply capability.
Lanthanum Oxide (chemical formula La₂O₃) is a fine white crystalline powder belonging to the lanthanide series of rare earth elements. With a molecular weight of approximately 325.81 g/mol, Lanthanum sesquioxide is recognized for its high melting point, high refractive index, and high dielectric constant (k). Due to these properties, it is used in glass manufacturing, electronics, catalysts, and ceramics. Also known as Lanthanum(III) Oxide or Lanthanum trioxide, the compound enhances glass refractive index, improves ceramic durability, and serves as a key ingredient in catalyst formulations for U.S. industrial manufacturers. Scimplify is a trusted Lanthanum Oxide manufacturer and supplier in the USA, delivering high-purity La₂O₃ (≥98.00%) complying with USA standards like TSCA (EPA) and NSF certification. With competitive USD pricing and bulk packaging or custom options, we provide the reliability and scale that U.S. customers expect from the best lanthanum oxide suppliers.
