High-purity Submicron Lanthanum Oxide (molecular formula: La₂O₃) is a high-performance rare earth oxide presenting as white fine powder, featuring strictly controlled submicron particle size (typically 0.1-1μm), ultra-high purity, and uniform particle size distribution. Distinct from nano lanthanum oxide (ultra-fine nanoscale) and conventional high-purity lanthanum oxide (coarse particle size), it balances the advantages of high activity (superior to conventional coarse powder) and easy processability (better than nano powder), with excellent chemical stability, thermal stability, and dispersibility. As a professional rare earth material supplier, we adopt advanced submicron particle size control and purification technology, implement strict quality inspection throughout the production process, ensuring each batch of products has consistent purity, uniform submicron particle size, low impurity content, and reliable performance. It is widely used in high-end ceramic sintering, catalyst support, optical glass modification, and electronic ceramic fields, serving as a core functional raw material for high-precision industrial production and high-tech applications.
Product Advantage
1. High Purity & Strict Impurity Control
Available in high purity grades (99.9% to 99.99%), with strictly controlled trace impurities and no harmful substances. The ultra-high purity ensures stable physical and chemical properties, avoiding adverse effects on the performance of downstream products, and fully meeting the high-standard requirements of high-end industrial and precision manufacturing applications.
2. Controlled Submicron Particle Size & Uniform Distribution
The product has a precise submicron particle size range (0.1-1μm), with narrow distribution and no obvious agglomeration. It balances high surface activity (better than conventional coarse lanthanum oxide) and easy processability (avoids nano powder agglomeration problems), making it suitable for various conventional processing technologies such as sintering, mixing, and coating.
3. Excellent Dispersibility & Compatibility
It has good dispersibility, can be quickly and uniformly dispersed in water, organic solvents, or various matrices (ceramics, catalysts, glass), and has strong compatibility with other materials. It does not affect the original performance of the base material, ensuring uniform performance of finished products.
4. Stable Physical & Chemical Performance
It has excellent thermal stability, high temperature resistance, and chemical inertness, not easy to react with air, moisture, or common chemicals. It can maintain stable structure and performance in high-temperature sintering and long-term storage, ensuring reliable application effect in harsh industrial environments.
