Boron Ignition Limit Curve as Determined by a Shock Tube Study.
Abstract
A shock tube was employed to establish ignition limit curves for two particle sizes of boron. The particles were ignited in air by the temperature rise behind the reflected shock wave. Results show that the ignition temperature for .015 micron particles increases linearly with pressure from 1130 K at 6 atm to 1170 K at 130 atm. For 30-50 micron agglomerated particles (1-2 micron primary size) the ignition temperature decreases initially to 1390 K at 20 atm but then increases linearly to 1420 K at 130 atm. In addition, preliminary information was obtained on ignition delay time for both particles. (Author)
