Lightening of Porcelain Body by Addition of Cerium Oxide

Abstract

Cerium oxide (ceria) was known as the material with oxygen storage and releasing capacity at high temperatures. Through this characteristic of ceria, we expected that the homogeneous dispersion of ceria in the porcelain body should be available for lightening of porcelain bodies. In this study, lightening of porcelain bodies was discussed by the addition of fine or coarse ceria particles. Lightening of porcelain bodies was achieved by introducing closed pores with the addition of fine ceria particles.
