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.

Semiconductor and microelectronics uses require ultra-high purity, typically 99.999% (5N) or higher, to prevent defects and ensure stable electrical properties in thin films.
Lanthanum Oxide is preferred in high-refractive index optical glass (like camera lenses) for its low dispersion. Cerium Oxide is mainly used for UV absorption and glass polishing.
Yes, its sourcing and processing are subject to regulations concerning rare earth mining, environmental impact, and potentially geopolitical trade restrictions.
When ingested, Laz O3 dissolves in stomach acid to form Lat cations, which bind strongly to dietary phosphate, forming an insoluble lanthanum phosphate complex that is then excreted.
Thermally stabilizeS the catalyst structure by inhibiting the phase transformation of high-surface-area y-alumina to the inactive, low-surface-area a-alumina phase at high temperatures.
High dielectric constant allows the fabrication of physically thicker films with equivalent electrical capacitance, reducing quantum tunneling and leakage current in modern logic and memory chips.
