Microwave sintering of NiCuZn ferrites and multilayer chip inductors

Microwave sintering technique was successfully applied for densifying (Ni 1- x- y Zn x Cu y ) Fe 2O 4 ferrite materials and multilayer chip (MC) inductors. This technique needs only 20 min at 850°C to obtain high-density materials (>95% TD) and high impedance MC-inductors (23.9 Ω). Moreover, char...

Zusammenfassung:Microwave sintering technique was successfully applied for densifying (Ni 1- x- y Zn x Cu y ) Fe 2O 4 ferrite materials and multilayer chip (MC) inductors. This technique needs only 20 min at 850°C to obtain high-density materials (>95% TD) and high impedance MC-inductors (23.9 Ω). Moreover, characteristics of the ferrite materials and MC-inductors are less sensitive to the processing parameters, as compared with those prepared by the conventional sintering technique.
