Аннотация
The minimum quantity of the high-activity chemical reagent (HACR) that is required for the initiation of self-propagating high-temperature synthesis (SHS) is determined. The experimental results show that 1–1.3 mg ClF3 (gravity flow from a dosing device), BrF3 on the end of a filling knife, or a few ClF2+ SbF6- crystals are sufficient for the initiation of titanium–boron or titanium–carbon high-energy powder charge compositions. Since the quantity of HACR required for SHS initiation is very small, the chemical method of initiation can be used for the development of a mobile ignition device for estimating the ignition of various SHS charge compositions under laboratory conditions and for application in standard reactors.
