Nano-cerium oxide
Ultra-fine ceria particles (below 20 nm) dispersed in water
Ultra-fine ceria particles (below 20 nm) dispersed in water
These nanomaterials can be used as polishing/CMP abrasive solution, in Solid Oxide Cells and also as nanofillers in composite materials.
Their high crystallinity, low organic content and narrow size distribution are key in these applications.
