Ceria Nanoparticles

High-Performance Nanoceria Dispersions

Cerion’s patented processes allow us to customize and manufacture 2-3nm ceria at industrial scale volumes. This size range has been proven to be the most reactive and thermodynamically stable for many applications.
 

Based on customer specifications, Cerion can:

• Manipulate surface charge, surface coating and offer a wide range of dopants
• Offer some of the tightest particle size distributions in the industry
• Guarantee at least 6-month stability for our commercialized dispersions
• Deliver ceria nanoparticles at up to 40% concentration in water over a wide pH range
• Shift nanoparticles into a wide variety of organic solvents
• Scale-up custom materials from 1,000 – 5,000x lab quantities in less than 6 months

 

Our high-performance ceria nanoparticles are available for optimization and incorporation into a myriad of industrial products and applications including:

• Catalysts
• Solid Oxide Fuel Cell Electrolytes
• CMP Slurries
• UV Absorbers
• Catalyst Supports
• Solar Cells
• Drug Delivery
• Anti-oxidants in Biological Systems
• Anti-corrosion Additives
• Sensors

Smaller is Better

While not the case for every material or application, in most products, the use of ultra-small nanoceria can improve performance and save money.

Compared to Bulk Ceria, Nanoceria has:

• Exponentially higher surface area
• Increased reactivity
• Optimal biocompatibility
• Superior UV-filtering properties
• Higher oxygen ionic conductivity
• Ability to scavenge reactive oxygen species (ROS) in biological systems
