Various factors affecting the electrical resistivity of the pyrotechnic pressed powder TiH/sub x//KC10/sub 4/, which is sensitive to hot wire ignition yet quite spark insensitive, were evaluated. The electrical resistivity of the TiH/sub x/ and TiH/sub x//KC10/sub 4/ were correlated with their pressing pressure, stoichiometry, powder surface area, and temperature (from below liquid nitrogen temperature to 500 K). Data show resistivity increasing with x and surface area, and decreasing non-linearly with pressing pressure. It was concluded that temperature coefficient of resistivity depends upon powder surface features. In addition, it was found that electrostatic discharge lowers TiH/sub x/ and TiH/sub x//KC10/sub 4/ pellet resistivity and that the effect is larger for pellets with higher initial resistivity.
