Application

Ceric Oxide is a highly monodisperse material, exhibiting a polydispersity index of less than 0.25, and is known for its significantly enhanced surface reactivity. It remains stable even at high suspension densities, provided it is used within the recommended pH range. This stability and reactivity make Ceric Oxide suitable for a wide range of applications, including emissions catalysis, fuel cell electrolytes, and the polishing of optical surfaces. It also finds use in the planarization of semiconductors and acts as a substrate for precious metals in oxidation catalysis. Additionally, Ceric Oxide is pivotal in catalysis for water splitting to produce hydrogen and serves as a radical oxygen scavenger in biological systems. As a cerium oxide-based compound, it is also utilized in optical and glass production, acting as a polishing agent and potential substitute for tin oxide, as well as in the manufacture and polishing of cathode ray tubes. It effectively decolorizes glass by altering the valence state of iron in the glass and functions as a catalyst substrate in automotive converters' oxidizing catalyst systems.
