Abstract
Received 30 June 2009, in revised form 28 September 2009 Abstract. The aim of this work is improvement of si nterability of aluminium nitride by combining spark plasma sintering with using nanosized particulate composites prepared by simultaneous evaporation of Al and Y2O3, Gd2O3 and YF3 additives in radio-frequency nitrogen plasma. This approach allows to fabricate fully dense AlN materials at 1400 °C with holding time of 2 min despite the reduction of rare-earth compounds and formation of YN and GdN phases in the plasma flow. Besides AlN phase, the prepared materials contain secondary phases aluminium oxynitride, Y3Al5O12, GdAlO3 or α -Al2O3, depending on the used additive.
