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.

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.
