This paper presents results of an investigation of the neck growth kinetics during microwave sintering of free-packed copper powder. Application of the classical sphere-to-sphere approach showed similarities between microwave and conventional sintering processes for long soaking times. Anomalous neck growth during the initial stage of microwave sintering was also revealed, which might be caused by a non-conventional diffusion mechanism.
