Lanthanum Oxide (La₂O₃) Nanopowder / Nanoparticles (99.99%, <200 nm)

Description

Lanthanum Oxide (La₂O₃) Nanopowder / Nanoparticles (99.99%, <200 nm)

Lanthanum Oxide (La₂O₃) Nanopowder is a high-purity white powder with particle sizes below 200 nm and exceptional chemical stability. With a purity level of 99.99% (REO basis), it is widely used in advanced materials research and industrial applications. The material exhibits a true density of 6.51 g/cm³ and very low impurity content, making it ideal for high-performance optical, electronic, and catalytic systems.

Lanthanum oxide nanoparticles have a high melting point (2217 °C) and boiling point (4200 °C). They are slightly soluble in water but readily soluble in acids, forming corresponding salts. When exposed to air, La₂O₃ absorbs CO₂ and moisture, transforming gradually into lanthanum carbonate.

Its strong catalytic behavior, optical transparency, and dielectric properties make La₂O₃ an essential component in high-tech industries.
