Paper Abstract

Tantalum oxide added MgCuZn ferrite powders were synthesized by a co-precipitation method using a microwave-hydrothermal (M-H) method. The phase identification of the prepared samples was characterized by X-ray diffraction and crystal size and morphology were determined by transmission electron microscopy (TEM). Nano-phase ferrites with high surface area were synthesized at 160°C after a treatment time of 1 hour. M-H synthesized powders were conventionally fired at a temperature of 900°C/4hrs. The variations of the sintered density, initial permeability and electrical resistivity as a function of additive concentration at room temperature have been investigated. The multi-layer chip inductors were fabricated using prepared ferrites. The prepared inductors posses better electrical properties than of multi-layer chip inductors prepared using the NiCuZn ferrites.
