Pyrotechnic blends of titanium powder with potassium perchlorate were shown to be less sensitive to electrostatic initiation in an atmosphere with high oxygen content than the titanium powder alone in the same atmosphere. Comparisons of data obtained for blends of titanium with various materials showed that it is unlikely that this desensitization is the result of physical dilution effects. It is proposed that a catalytic interaction between the titanium oxide coating on the metal particles and the potassium perchlorate lowers the activation energy for the decomposition of the oxidizer while increasing the activation energy for the initiation reactions involving titanium (oxide). 2 figures, 3 tables.
