Abstract
A precise, slow burning, pyrotechnic delay composition composed of a ternary system of from about 8 to about 55 weight percent B4C fuel, 35 to about 82 weight percent NalO4 oxidizer, and PTFE which acts as a pyrotechnic oxidizer and lubricant—such that the resulting composition has surprisingly good mechanical properties, i.e. it can be pressed to a desirably high consolidated density with ordinary loading force, and with minimal wear on the tooling used for pressing.
Claims11
An environmentally friendly and easily compressed pyrotechnic delay composition, comprising:
- a ternary mixture of B4C (boron carbide), NalO4 (sodium periodate), and PTFE (polytetrafluoroethylene);
- which mixture has an inverse burning rate from about 1.3 to about 20.8 s/cm when pressed into a consolidated column.
