Abstract :
Barium hexaferrites BaFe12O19 with Bi2O3/CuO additives are synthesized in this study by conventional oxide ceramic process and characterized using SEM. Saturation magnetization and remanence properties are determined as the amount of additives is varied. It is shown that the additives segregate in the grain boundary regions, and significantly promote grain growth and sintering densification.
