Abstract

Abstract Al 2 O 3 –MoSi 2 composites with MoSi 2 volume fractions between 16 and 40% were fabricated from commercial ceramic Al 2 O 3 and intermetallic MoSi 2 powders by granulation, cold isostatic pressing and vacuum-sintering. The addition of MoSi 2 had only a slight influence on the densification of the composites, with sintered densities of 98% for samples with 16 vol.% MoSi 2 and 94% for samples with 40 vol.% MoSi 2 . Composites with MoSi 2 contents of 20 vol.% and higher were electroconductive due to the formation of a three-dimensional percolating network of the conductive MoSi 2 phase.
