Core-shell structured BaTiO3 powders were produced via nano-coating of Cr2O3 and Mn2O3 to barium titanate powder system for MLCCs. From preliminary experiments, the optimal solution reaction condition employing using KMnO4, K2Cr2O4 and sulfur was established. Not only powders of Cr2O3 and Mn2O3 were synthesized but also their coating on BaTiO3 powders were peformed under the same reaction condition. The coating was carried out in two ways, one-step and two-step, and its results were characterized for comparison. Conclusively speaking, two oxide additives were coated onto the BaTiO3 powder surface with high quality and excellent reaction yield even under mild condition, which indicates that the contents as well as the properties of additive shell layer can be precisely controlled with rather ease.
