Abstract: TiB₂ powders were synthesized by the thermal explosion mode of self propagating high temperature synthesis(SHS) from Ti(or TiH₂),Al and B powders.The effects of TiH₂ powders and synthesis temperature on the process of TiB₂ combustion reaction were studied.The mechanism of TiB₂ formation were discussed.
