Abstract

The influence of an electric field on the combustion synthesis of ${Ti}_{5}{Si}_{3}$-x ${ZrO}_{2)$(0 $\leq$ x $\leq$0.6)was investigated. Composite of X $\geq$0.45 can only be synthesized in the presence of an electric field. Although in the absence of an electri field the system with x = 0.45 and x=0.6 can sustain a nonsteady combustion wave, the reaction is not complete. That is, an unstable wave propagates to the middle of the sample and them becomes extinguished. Wave velocity o the ${Ti}_{5}{Si}_{3}-{ZrO}_{2}$ Composites slightly increases with the imposition of external field across the sample.
