Autor: Csaba Balazsi, Ferenc Weber, Zsolt Kasztovszky

Publikováno v: Communications, Vol 6, Iss 1, Pp 5-9 (2004)

Carbon black and graphite nano/micrograins and sintering additives (Al2O3 and Y2O3) were added to silicon nitride starting powder. These mixtures were mechanochemically activated several hours in a planetary type alumina ball-mill in order to achieve
