Al 2 O 3 , SiC and kaolin were employed as additives in combustion synthesizing Al 2 O 3 -TiB 2 ceramic composite. Effects of the additives on adiabatic temperature, combustion wave velocity, volume change and composite density were studied, and bending strength of the synthesized ceramics was evalu
## A bstra ct AI203-TiB 2 composites containing 0-50 wt% TiB 2 were prepared by sintering at 1600-1750Β°C ,for 15-120min in a vacuum. Relative density increased with TiB 2 addition from 97% (no TiB2) to about 99% ( lO-40wt% TiB2) on sintering at 1750Β°C Jbr 60 min. TiB 2 behaved as a sintering aid t
