摘要
研究了葡萄糖酸钙的加入时间对细磨效果及锶铁氧体磁性能的影响,用激光粒度分布仪、SEM和VSM分析样品的粒度分布、微观形貌、取向度及磁性能.研究结果表明:葡萄糖酸钙能有效地提升材料的磁性能,并且分散剂的加入方式也对材料磁性能产生明显影响;在细磨前和细磨后分别加入质量分数为0.3%和0.1%的分散剂的方式下,锶铁氧体可得到最优磁性能,其中Br=443.6 mT和Hcj=359.5kA/m.
The effect of adding time of calcium gluconate on the fine grinding effect and magnetic properties of the material was studied. The particle size distribution, microstructure, orientation and magnetic properties of the samples were analyzed by laser particle size distribution analyzer, SEM and VSM. The results show that calcium gluconate can enhance the magnetic properties effectively, and dispersing agent mode the effects of material properties. Calcium gluconate with mass fraction of 0.3% and 0. 1% was added before and after fine grinding respectively, strontium ferrite can be obtained for the optimal magnetic properties, where Br=443.6 mT and Hcj =359.5 kA/m.
