Description

General description

Cerium(IV) oxide (CeO₂) is a class of rare earth materials which can be synthesized by a variety of methods which include thermal hydrolysis and hydrothermal method. Its properties include a high refractive index, and dielectric constant.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is intended for Molecular Solar Thermal Energy Storage Systems (MOST) and has been enhanced for energy efficiency. Click here for more information.

Application

CeO₂ nanopowder can be used for a variety of applications such as biomedicine, semiconductors, and coating applications.

The additon of CeO₂ to CuO/TiO₂ increases specific surface area and inhibits sintering and pore size growth at high temperatures.
