Abstract
The densification of Al2O3-30TiC (in weight percent) composite is inve stigated as a function of Y2O3 additions. It is observed that very sma ll amounts of Y2O3 are effective in aiding the densification. The dens ity was observed to pass through a maximum at 0.35 wt% of Y2O3. The ga s-generating reaction of Al2O3 with TiC is likely to be suppressed by the addition of Y2O3.
