摘要：

Tantalum oxide added MgCuZn ferrite powders were synthesized by a co-precipitation method using NaOH in a microwave-hydrothermal (M-H) apparatus. The phase identification of the prepared samples was done 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 degrees C after a treatment time of 1 hour. The M-H synthesized powders were conventionally sintered at a temperature of 900 degrees C/4h. The variations of the sintered density, initial permeability and electrical resistivity as a function of additive concentration at room temperature have been investigated.
