Consolidation of Si3N4/SiC Whisker Composites by Colloidal Filtration
Published online by Cambridge University Press: 25 February 2011
Abstract
Stable Si3N4/SiCw co-dispersions containing up to 20 wt.% of whiskers have been prepared. Homogeneous green bodies with relative green density above 55% and pore size in the range 40-50 nm have been obtained by pressure assisted colloidal filtration. By optimizing the temperature and/or the amount of sintering additives, densities above 90-95 % have been achieved by pressureless sintering of these consolidated compacts.
