Microwave sintering is a technique with a huge potential for the manufacture of a variety of ceramic materials with controlled ceramic microstructure. The objective of the present work was the microwave sintering of NiFe2O4 in a microwave oven. In this research, we used a NiFe2O4 synthesized by Pechini method. Samples of this powder were sintered by the conventional and microwave process, and characterized by X-ray diffraction and scanning electron microscopy, and their density and magnetic properties were also determined. The microwave sintering process took less than 10% of the time required for conventional sintering, and the samplebulk density and saturation magnetization values were similar to those observed forthe conventional sintered ones.
