COMBUSTION OF ELEMENTAL BORON
Abstract
Studies of the reaction between elemental boron and fluorine gas continued in both the low-pressure microbalance apparatus and in the time-of-flight mass spectrometer. Corrosive failure of the mass-spectrometer apparatus prevented obtaining the refined data hoped for in the 800 to 1600 deg K temperature range, although the data available do indicate that at these temperatures BF was the principal species formed on the surface AND THAT THE REACTION APPARENTLY CHANGED TO A LOWER ACTIVATION ENERGY MECHANISM WHEN THE TEMPERATURE WAS RAISED TO ABOUT 800 deg K. Rates obtained in the 525 to 630 deg K range in the microbalance apparatus gave an activation energy of about 19 kcal/mole, which suggests that the ratecontrolling step in this region might be the dissociation of fluorine as it is adsorbed on the surface.
