The search for new ceramic pigments is now a high-priority field in the ceramics industry because of the scarce variety of existing ones and the limitation imposed on their use by the current technological and ecological requirements [1,2]. The rare earth oxides, which are believed to be less toxic compared with transition metal ions, have a bright appearance and have potential to form ceramic colors. Research in the fields of ceramic pigments is oriented toward the enlargement of the chromatic set of colors together with an increased thermal and chemical stability. Pigments based on cerium dioxide are lesser known and represent only a small, but an important range of inorganic pigments. As pigments of red to orange hue, sulfides of Ce3+ (4f1 5d0 ) ions such as g-Ce2S3 and its alkali-metal derivatives g-Ce2xA3xS3 (A = alkali) have been proposed [3– 5]. Pr-doped ceria pigments [6] give various pink-orange to redbrown hues, depending on the quantity of praseodymium,
