Description

Lanthanum Oxide (La₂O₃) Micron Powder, Purity: 99.5+%, Size: -325 mesh

Product Description:
Lanthanum Oxide (La₂O₃) Micron Powder with purity exceeding 99.5% and a fine -325 mesh particle size is a high-performance rare earth oxide powder widely used across advanced material industries. It features excellent thermal stability, alkaline properties, and optical transparency, making it a versatile component in both functional and structural material systems.

Lanthanum Oxide is a white, odorless, and hygroscopic powder with a hexagonal crystalline structure that reacts readily with moisture and carbon dioxide in the air, forming lanthanum hydroxide or carbonate. This characteristic makes it especially valuable in chemical synthesis and catalytic processes.

In the catalyst industry, La₂O₃ is used to enhance combustion rates and improve the efficiency of propellants and automobile exhaust treatment systems. Its high dielectric constant and optical clarity make it suitable for use in piezoelectric materials, optical glass, electrode materials, and light-emitting phosphors. Lanthanum Oxide also finds use in laser materials, photoelectric conversion films, and hydrogen storage alloys.

The sub-44 µm particle size ensures a large surface area for reactions, high dispersion in matrices, and superior sinterability when used in ceramics and glass production. Its ability to form stable lanthanum-based compounds makes it a foundational material in the rare earths industry.
