技术领域
本发明属于磁性材料领域,具体涉及一种低损耗锰锌铁氧体的制造方法。
背景技术
随着电力电子技术的不断进步,电子整机系统向小型轻量化、多功能化、平面贴装化、集成数字化以及智能化等方向发展,在一般的应用对于绿色、高效能的要求越来越高,而更为重要的是为了适应全球不同环境的应用,要求电源不仅要适应高温的环境,同时也要适应超低温的环境,这样对其中磁性材料的要求也就越来越高,要求磁性材料不仅在高温下、同时在常温甚至在超低温下都有较优越的低损耗性能。
发明内容
本发明的目的是克服现有锰锌铁氧体在极端温度特别是超低温下功率损耗大的问题,提供一种低损耗锰锌铁氧体的制造方法。
本发明实现上述目的所采用的技术方案如下:
一种低损耗锰锌铁氧体的制造方法,步骤如下:
(1)锰锌铁氧体的主料的组分:52~55mol% 氧化铁、37~43mol%四氧化三锰,余量为氧化锌,将主料进行一次砂磨,在一次砂磨时掺入Co3O4,以及TiO2、Ni2O3和SnO2中的至少一种,总掺入量为主料总质量的1000~5000ppm;
(2)一次砂磨后的颗粒进行预烧,温度为850-980℃;
(3)预烧后进行二次砂磨,并掺入Ta2O5和SiO2,以及Nb2O5、ZrO2、CaCO3、和V2O5中的至少一种,总掺入量为主料总质量的700~1200ppm;
(4)二次砂磨后造粒,成型;
(5)烧结,保温温度为1150-1250℃,氧分压为3-6%。
进一步,步骤(2)的预烧在回转窑炉进行。
进一步,步骤(3)二次砂磨后颗粒的平均粒径为0.7-0.9微米。
进一步,步骤(5)保温时间为3~5小时。
与常规磁芯相比,按本发明所述方法制得的锰锌铁氧体磁芯在-25~100℃范围内具有更为稳定的功率损耗,特别是在室温至-25℃的低温范围内,功率损耗有显著降低,如-25℃时,功耗下降20%。
附图说明
