Difference of Magnetic Pulse Compaction from Traditional Uniaxial Pressing of Alumina Nanopowders

Processes of pressureless sintering of alumina nanopowders, subjected to traditional uniaxial pressing or magnetic pulse compaction, were investigated with the use of X-ray diffraction, scanning electron microscopy, thermal analysis and dilatometry. In this study sintering mechanisms, initiated by magnetic-pulse compacting and absent in the classical compaction, for the first time were found.
