预烧与烧结对MnZn功率铁氧体磁性能的影响
Effects of Presintering Temperatures and Sintering on Properties of Low Power Loss Mn-Zn Ferrites
【摘要】 该文主要研究了不同的预烧温度和烧结适配对MnZn铁氧体磁性能的影响.作者发现,780℃的预烧温度有利于烧结过程中固相反应的进行,提高样品密度,改善样品性能.与传统的烧结过程相比较,作者在降温过程中采用的二次还原法烧结过程,产品性能更优.
【Abstract】 Effects of different presintering temperatures and sintering on the manganese-zinc ferrites with low power loss are studied with X-ray for measuring magnetic properties.It has been found that better properties can be obtained at a presintering temperature of 780 ℃.Compared with the traditional method,a double reduction method used in the cooling process leads to better quality of the ferrites.
