Abstract

This paper presents results of an investigation concerning neck formation during microwave sintering of copper powder. Porous copper samples were treated in single-mode and multimode microwave furnaces in order to investigate neck formation process. Samples were heated to temperatures as high as 0.8T_mp in 2.45 GHz microwave field. Evidence of pure microwave effect on initial stage of sintering was found on fracture surface of sintered samples, as development of micro-plasma discharges in porous material seem to enhance sintering process.
