摘要

We investigate the effects of B2O3 addition on structural and magnetic properties of hard magnetic BaFe12O19 particles.The conventional solid state reaction method is used as the synthesis route.Single phase BaFe12O19 could be synthesized with very small amounts of B2O3 addition and with calcination at low temperatures(850℃)in short times(1 h).B2O3 addition also improves the magnetic parameters significantly.Remanence magnetization and specific magnetization at 1.5 T increase by ～ 40% in magnitude although no significant variations on coercivity is observed.
