Description

Cerium(IV) 2-Methoxyethoxide, 18-20% w/w in 2-Methoxyethanol is a high-purity, organometallic precursor solution containing cerium in the +4 oxidation state. This compound is critical for depositing cerium oxide (ceria) thin films with precise stoichiometric control, which is essential for advanced material performance. It is primarily utilized by manufacturers and researchers in the electronics, catalysis, and specialty glass industries for applications requiring high-k dielectrics, oxygen storage components, and optical coatings.

Application

• Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD): As a key precursor for the fabrication of cerium oxide (CeO2 or ceria) thin films in semiconductor and microelectronics manufacturing.
• Catalyst Synthesis: Used in the preparation of advanced oxidation catalysts for automotive exhaust systems and industrial processes.
• Sol-Gel Processing: For the production of high-purity ceria nanoparticles and doped ceria materials used in solid oxide fuel cells (SOFCs) and oxygen sensors.
• Optical Coatings: Serves as a starting material for coatings with specific refractive indices and UV-blocking properties for lenses and specialty glass.
• Surface Modification: Applied in research and development for creating cerium-based functional surfaces with corrosion-resistant or catalytic properties.
• Polymer and Ceramic Additive: Acts as a dopant or cross-linking agent in the synthesis of specialty polymers and advanced ceramic composites.
