摘要：

Low temperature sintering (Ni/Mn)CuZn ferrite was employed at most cases due to its co-firability with Ag (below 960 degrees C). The purpose of this study is to fabricate (Ni/Mn)CuZn ferrite sintered body with high-strength and high-frequency magnetic proper-ties. Following is the procedure: firstly, (Ni/Mn)CuZn ferrite powder was synthesized under CO2 atmosphere at 500 degrees C from the mixed doxalate synthesized by co-precipitation method; then a small amount of boric acid [H3BO3] was added to the powder, and the (Ni/Mn)CuZn ferrite powder compact was prepared with Newton press and CIP methods; finally, (Ni/Mn)CuZn ferrite sintered body was fabricated by sintering at 900 degrees C under CO2 atmosphere. By this method, NiCuZn and MnCuZn ferrite sintered bodies with 0.5 mass% boric acid were obtained, the strength are 430 and 530 MPa respectively. The effect of various Mn addition on NiCuZn electromagnetic properties were studied.
