Shock initiation of pyrotechnic materials is becoming increasingly more interesting since this concept is now used in weapon component design. In this study we have performed several types of shock initiation experiments on TiH/sub 0/ /sub 65//KC10/sub 4/ to better understand its shock response and the process by which it undergoes reaction. Gas gun impact experiments have led to new unreacted Hugoniot information which was used, along with earlier reported data, to construct an equation of state for the unreacted material. Particle velocity records of the projectile impact interface and the shock transmitted through the sample show little evidence of reaction in the first microsecond even for 6 GPa shocks. Peculiarities in the waveforms at later times suggest some evidence of reaction although the experiments do not remain strictly one-dimensional long enough to make definite statements. Flyer plate initiated compacts indicate a short input pulse is rapidly attenuated but the material is initiated and a combustion wave propagates through the compact at velocities of about 0.4 to 0.7 km/s.
