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.
