Description & Features

Descriptive: WNX employs advanced automated production technology and uses high-quality raw materials to produce high-quality Large Particle Size Cerium Oxide.

Key Features:

High Purity:Large Particle Size Cerium Oxide

contains no impurities from rare earth elements (such as iron, calcium, sodium), and the impurity content is low.

Good Solubility: Large Particle Size Cerium Oxide

can dissolve rapidly in water and strong acids.

Consistency: The strict batch management in the production of Large Particle Size Cerium Oxide

ensures stable quality for industrial large-scale production.

Chemical industry catalysts: The Large Particle Size Cerium Oxide, due to its superior mechanical strength and stability, is used as an excellent catalyst carrier in fixed-bed reactors that need to withstand high pressure or high-speed airflow impacts. It can effectively load precious metals (such as platinum and palladium) and is used in processes such as hydrogenation in petrochemicals, significantly extending the service life of the catalyst. Its unique oxygen vacancy defect characteristics also make it play an important role in vehicle exhaust purification (three-way catalytic converters), promoting the conversion of carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx).

Pond Phosphorus Removal Agent: The Large Particle Size Cerium Oxide particles can effectively adsorb and precipitate phosphate ions in the water body, thereby inhibiting the growth of algae and solving the problem of water body eutrophication. The particle size is relatively large, and its sedimentation performance is better in actual water body applications, making it easier for subsequent recovery and reducing the risk of secondary pollution.

Batteries and Energy Materials: In solid oxide fuel cells (SOFCs), Large Particle Size Cerium Oxide can be used as an electrolyte material. Its high grain boundary stability helps to enhance the ionic conductivity and the long-term operational durability of the battery. Additionally, it can also be used as a raw material for preparing hydrogen storage alloys for the negative electrode of nickel-hydrogen batteries, or for modifying lithium-ion battery electrode materials, thereby improving the cycling performance of the battery through its stable structure.

Chemical synthesis intermediates: Large Particle Size Cerium Oxide is an important precursor material for synthesizing other cerium-based functional materials (such as cerium salts, doped cerium oxide, etc.). Through further chemical processing, it can be transformed into cerium compounds with specific morphologies and properties, which are used in fields such as electronic ceramics and ultraviolet absorption materials.
