Ceramic nano pigments have attracted much interest owing to recent demand for nontoxic, heavy metal-free pigments. In general, ceramic pigments must possess thermal stability at high temperature, however nanosized powder easily undergoes aggregation at high temperature, and its color turns. serveral groups have focused on to minimize agglomeration and oxidation, a core–shell structure with a silica coating is suggested. In this review, we introduce the reported the trend of nano-ceramic powders and we summarized method improve color and physical properties throuth morphology control and ceramic coating technology.
