【摘要】 多层片式电感器(MLCI)所用铁氧体材料,其粒度的均匀、正态分布水平,是影响元件成型过程中分散性的关键因素。通过对铁氧体粉料分级球磨技术的研究,实现了片感用铁氧体粉料的均匀、正态分布,平均粒径在0.8μm左右,在粘结剂中具有良好的分散性;同时,利用分级球磨技术还可以缩短生产时间,提高生产效率。更多还原

【Abstract】 Particle uniformity and normal distribution of ferrite powder used in multilayer chip inductor are the key factors affecting the electronic component shaping.Grading ball milling was studied to realize particle uniformity,normal distribution,average particle size was about 0.8 μm and good disperability when ferrite powder made into slurry.Grading ball milling can also shorten production time and raise efficiency of production.更多还原
