A Brief Discussion on the Research of Ultrafine Lanthanum Oxide Powder

Rare earth elements are known as a treasure trove of new materials and "industrial vitamins" due to their unique 4f electronic structure. Rare earth oxide powders are a hot spot in the current development of rare earth materials. Particle size distribution is a very important performance indicator of rare earth oxide powders, which affects the different application ranges of rare earth oxides.

Lanthanum oxide (La₂O₃) is one of the important products of light rare earth. Due to its good physical and chemical properties, it has been widely used in civil, military and high-tech fields. For example, the application of La₂O₃ in rare earth glass, ceramics, catalysts, phosphors, lasers, heating elements, cathode materials and electrical contacts is developing continuously and has a promising future.

At present, there are traditional methods for preparing lanthanum oxide powder, such as solid phase method, precipitation method, hydrothermal method, sol-gel method, etc., as well as new research methods such as reverse emulsion method, low-temperature combustion method, carbon dioxide carbonization method, etc. Among them, the reverse precipitation method is used to effectively control the reaction process and crystal growth by adjusting the reaction temperature, solution pH, and dispersant type, and obtain lanthanum oxide ultrafine powder with small particle size and narrow particle size distribution.

Suzhou KP Chemical Co., Ltd can provide Lanthanum oxide of different particle sizes such as Lanthanum oxide (La₂O₃) with purity La₂O₃/TREO: 99.99% or 99.999%, Lanthanum oxide (La₂O₃) with particle size D₅₀：<1.5um, Lanthanum oxide (La₂O₃) with particle size D₅₀：1.5-2.0um，and Lanthanum oxide (La₂O₃) with particle size D₅₀：3.5-5.5um.
