Investigation of the Low Temperature Sintering Technology of NiCuZn Ferrite with Different Additive

摘要

In this paper, the sintering process of NiCuZn ferrite sintered at 1000 degrees C similar to 1100 degrees C was investigated, and the microstructure without additive is reasonable at 1100 degrees C. The morphology with additive of 1% ferric oxalate is satisfied at 1080 degrees C. So, the sintering temperature of NiCuZn ferrite can be decreased by 20 degrees C with the additive of ferric oxalate. The morphology with additive of 1% boronic acid is satisfied at 1050 degrees C. So, the sintering temperature of NiCuZn ferrite can be decreased by 50 degrees C with the additive of boronic acid. We also found that the cooling effect with boronic acid is better than that with ferric oxalate and there is no phase transformation during the sintering process from powder to sintered body. Better properties can be achieved by using high purity raw materials and strictly controlling the main prescription and production technology.
