B 4 C-SiC-Si-TiB 2 composites were synthesized by a two step process. TiB 2 particles in the size range 2-5 m were generated in situ in the first step and were distributed in the residual silicon present in the reaction bonded boron carbide, in the second step. The composites were characterized by X
## 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
