Preparation of induction heating element having self-temperature controllability

高频磁场下的发热材料由磁性半导体锰锌铁氧体、PTC半导体铈掺杂钛酸钡（CBT）和低软化温度玻璃组成。研究了它们的电、磁和发热性能。铁氧体的涡流损耗主要参与高频磁场下的发热。复合材料的发热量与铁素体的含量有关。但是，该复合材料在控制铁氧体涡流方面不能推广

Heat generation materials under high frequency magnetic field were composed from manganese-zinc ferrite of magnetic semiconductor, cerium doped barium titanate (CBT) of PTC semiconductor and glass of low softening temperature. Their electric, magnetic and heat generation properties were investigated. The eddy current loss of the ferrite was found to mainly participate in the heat generation under high frequency magnetic field. The composite materials showed the heat generation in accordance with the content of ferrite. However, the composite could not be extended in controlling the eddy current of the ferrite
