Description & Features

Descriptive: WNX employs advanced automated production technology and uses high-quality raw materials to produce high-quality Fine Crystalline Spherical Cerium Carbonate .

Key Features:

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

Good Solubility: Fine Crystalline Spherical Cerium Carbonate can dissolve rapidly in water and strong acids.

Consistency: The strict batch management in the production of Fine Crystalline Spherical Cerium Carbonate ensures stable quality for industrial large-scale production.

Chemical industry catalyst: Fine crystalline spherical cerium oxide has a high specific surface area and a regular spherical morphology, making it an excellent precursor for the preparation of efficient automotive exhaust purification catalysts and petroleum catalytic cracking (FCC) catalysts. Its uniform particle size is conducive to improving the efficiency and stability of the catalytic reaction.

High-end optical polishing material: Fine Crystalline Spherical is the key precursor for manufacturing high-performance cerium oxide polishing powder. Its spherical particle shape can effectively reduce scratches during the chemical mechanical polishing (CMP) process, achieving an ultra-smooth surface (roughness Ra < 0.5 nm). It is particularly suitable for polishing of precision optical glass and semiconductor wafers (such as shallow trench isolation STI process).

Electronic Ceramics and Functional Materials: Fine Crystalline Spherical is used as additives to prepare multilayer ceramic capacitors (MLCC), special ceramics, and fluorescent materials. Their fine spherical structure helps improve the density, thermal stability, and dielectric properties of ceramics, and can also be used to synthesize cerium-doped luminescent materials.

Chemical synthesis intermediate: Through high-temperature calcination, Fine Crystalline Spherical can be transformed into high-purity cerium oxide (CeO₂), maintaining its spherical morphology. This characteristic makes it of great value in the synthesis of energy materials (such as electrolytes for solid oxide fuel cells), ultraviolet absorption materials, and nano-functional materials.
