Tempering process for reducing loss of sintered magnetic core of high-frequency MnZn ferrite
The tempering process for reducing the loss of the high-frequency MnZn ferrite sintering magnetic core is characterized in that the tempering temperature is kept between (Tc-150) DEG C and (Tc+150) DEG C, and the tempering temperature is kept above 150 DEG C. Wherein Tc is the Curie temperature of the ferrite magnetic core. The cooling rate after tempering is 60 DEG C/hour or less.
一种降低高频MnZn铁氧体烧结磁心损耗的回火工艺，其特征在于：回火保持温度在（Tc‑150）℃至（Tc+150）℃之间，且回火保持温度在150℃以上。其中Tc为铁氧体磁心的居里温度。回火后的降温速率为60℃/小时及以下。
