Description & Features

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

Key Features:

High Purity:Large Particle Size Cerium Carbonate contains no impurities from rare earth elements (such as iron, calcium, sodium), and the impurity content is low.

Good Solubility: Large Particle Size Cerium Carbonate can dissolve rapidly in water and strong acids.

Consistency: The strict batch management in the production of Large Particle Size Cerium Carbonate ensures stable quality for industrial large-scale production.

Chemical industry catalyst: Large-particle cerium carbonate is an important precursor material for preparing automotive exhaust three-way catalysts. Through high-temperature calcination, it can be transformed into cerium oxide with high oxygen storage capacity, thereby effectively promoting the catalytic purification reactions of carbon monoxide, hydrocarbons, and nitrogen oxides.

Efficient Phosphorus Removal Agent: Based on the high affinity between cerium ions and phosphate ions, large-particle cerium carbonate can be used as a phosphorus removal agent for water treatment and the restoration of eutrophic water bodies. Its large particle size enables better sedimentation performance in practical applications, facilitating separation and recovery, and effectively reducing the total phosphorus concentration in the effluent to an extremely low level (e.g., from 0.55 mg-P/L to ≤ 0.03 mg-P/L).

Ceramics and Polishing Materials: Large-grained cerium carbonate is a key raw material for manufacturing special ceramics (such as electronic ceramics) and high-performance polishing powders. Its larger particle size helps to achieve a smoother polishing surface, which is crucial in the chemical mechanical polishing (CMP) of optical glass and semiconductor wafers. It can also be used as an additive in hard alloys to enhance the material's performance.

Chemical synthesis intermediates: As an important precursor for cerium compounds, large-grained cerium carbonate is used to synthesize various cerium salts (such as cerium nitrate, cerium chloride, etc.) and ultimately to prepare high-purity cerium oxide. By strictly controlling the precipitation conditions (such as the concentration of the rare earth solution, reaction temperature, and aging time), the particle size of the product can be controllably adjusted (the central particle size D50 can reach approximately 150 μm), meeting the specific requirements of different downstream applications for the particle size of the raw materials.
