采用不同厂家的NiO原料制备的NiZn铁氧体性能对比

Property comparisons between NiZn ferrites prepared using NiO raw materials of different suppliers

采用传统氧化物法制备NiZn铁氧体材料,考查不同厂家的NiO原料对于高性能NiZn铁氧体材料电磁性能的影响。实验表明,NiO原料的纯度、颗粒尺寸、颗粒形貌严重影响材料的烧结活性和电磁性能。高纯度、颗粒尺寸较均匀、形状为松果状的NiO原料是制备高性能NiZn铁氧体材料的最佳选择。

In this research, conventiorml oxide ceramic method was used to prepare NiZn ferrites, and the effect of NiO raw materials of different suppliers on the magnetic properties of corresponding materials was studied. The experimental results showed that the purity, particle size and surface morphology of NiO raw material seriously affect the reactivity and magnetic properties of the prepared materials. NiO raw material with high purity, homogeneous particle size and pinecone shape is the best choice for preparing high performance NiZn ferrite.
